The following contains halachic guidance concerning some of the common issues that arise when conducting a Pesach Seder. In particular, it discusses preparation for the Seder, the four cups of wine, and the obligation to eat matzah, marror, korech and Afikoman. This is by no means comprehensive. For a more comprehensive guide, see HaSeder HaAruch by Rabbi Moshe Yaakov Weingarten (three volumes, 1431 pages).
Preparations for the Seder
A person should complete all of the necessary preparations for the Seder on Erev Pesach to enable him to start the Seder without delay.1 (If Erev Pesach falls on Shabbos, he cannot prepare for the Seder on Erev Pesach since he may not prepare for Yom Tov on Shabbos, from one day of Yom Tov for the next day.)
The following preparations should be made prior to Yom Tov:
1.If meat will be eaten at the Seder, it may not be roasted. Meat cooked with a quarter inch or more of water at the bottom of a pot is not considered to be roasted and may be eaten at the Seder.2
2. If horseradish is being used for marror, it should be grated.3 If one forgot to do this, then he may grate it on Yom Tov if he employs a shinui and grates in an unusual manner, such as grating it onto the table rather than onto a plate.4
3. If lettuce leaves are being used for marror, they should be checked to ensure that they are not harboring insects.5 To check romaine lettuce leaves, one method is to separate the leaves, soak them in water, and then make a thorough leaf-by-leaf inspection. Any insects which are found must be removed. (For another method of checking, see here.) Alternatively, he may use romaine stalks for marror instead of the leaves. 6 To do this, he should remove the leaves from the stalks and rinse them under a strong stream of water, while rubbing the stalks during the rinsing. No further checking is required.
4. Prepare the karpas vegetable and the salt water into which it will be dipped.7 Any vegetable may be used for karpas, except those which may be used for marror.8 However, the custom is to use celery,9 radishes,10 or cooked potatoes.11
5. Prepare the charoses.12 The ingredients for charoses typically include grated apples, almonds and other nuts,13 cinnamon, ginger, and red wine.14 The charoses should have the texture of apple sauce.15
6. The bone which will be used for the zroa on the Seder plate should be roasted over a fire, as was done to the Korban Pesach.16 Some people first boil the zroa and then singe it over a flame.17 It is preferable to use the forearm of an animal or bird, which is the zroa bone.18 The equivalent limb of a chicken is the part of the wing that is directly attached to the body.19 The zroa must have some meat on the bone.20 It may not be eaten on Seder night because we do not eat roasted meat at the Seder.21 The meat of the zroa (which has been cooked before Yom Tov) should ideally be eaten on the second day of Yom Tov, as it is not proper to dispose of the zroa in an unfitting manner.22
8. Open the wine bottles to be used at the Seder. In particular, wine bottles that have a screw cap should be opened before Yom Tov.25 One should also open the boxes of matzah that will be needed for the first days of Yom Tov.26
10. Set the Seder table with elegant dishes and arrange the chairs which will be used for leaning.29 Even though throughout the year one should minimize luxury as a zecher l’churban, on Seder night it is appropriate to use the finest dishes available.30 Some people have a custom that the husband arranges the Ke’arah.31 There were gedolim who insisted on personally setting the table for the Seder.32
11. Prepare the Ke’arah. There are differing customs as to the layout of the various components of the Ke’arah. One prevalent custom is that of the Arizal.33 According to this minhag, beginning at the top of the Ke’arah is the zroa, which is placed on the upper right side of the Ke’arah, and the beitzah which is placed on the upper left side. The marror is placed in the middle of the Ke’arah, with the charoses underneath and to the right, and the karpas underneath and to the left. The chazeres is placed closest to the leader of the Seder, at the bottom of the Ke’arah. Three matzos are placed either outside or underneath the Ke’arah,34 next to the zroa and beitzah.35 Another custom is that of the Rema.36 According to this minhag, the karpas and salt water are placed nearest the leader of the Seder with the matzah above them, the marror and charoses above the matzah, and the beitzah and zroa above them furthest from the leader of the Seder.
Below is an illustration of the Keara according to both the Rema and the Arizal.
Some have the custom to place a covering between each of the three matzos, while others do not.39 The matzos should be covered before Kiddush.40 Often, families that join together for the Seder have the custom of providing a separate Ke’arah for the head of each individual household.41
12.Make an eruv tavshilin, if necessary. One should take a baked item such as matzah and a cooked item 42 such as fish, meat or an egg.43 He should hold the items44 and recite the text found in the siddur. The eruv tavshilin should not be eaten until all of the preparations for Shabbos are completed.45 It is customary to eat the eruv tavshilin at shalosh seudos.46
The Four Cups
One is required to drink four cups of wine at the Seder;47 women have the same obligation as men.48 If a person drinks four cups of wine in a row, he is not yotzei this mitzvah.49 Rather, he must recite the Haggadah and drink each of the arba kosos at the appropriate point.50 For this reason, he may not drink the fourth cup immediately after the third cup.51 A woman should make sure that she either recites the Haggadah herself or hears the leader of the Seder recite the Haggadah, so that she will be able to drink the arba kosos at the appropriate times.52
The cup should hold the measurement of a reviis of wine.53 According to Rav Chaim Noeh, a reviis is calculated at 86 cubic centimeters of wine,54 which is equivalent to slightly less than 3 fl. oz. According to the Chazon Ish, it equals 150 cubic centimeters of wine which is equivalent to slightly more than 5 fl. oz.55 Based on the ruling of the Mishnah Berurah, Rav Heinemann shli”ta,56 states that it is necessary to use a cup which holds 3.8 fluid ounces.57
Ideally, a person should drink a reviis of wine.58 Some opinions state that if the cup holds more than a reviis he should drink the entire cup;59 others dispute this.60 If it is difficult to drink an entire reviis of wine, one should drink slightly more than half the cup.61 If a person has difficulty drinking four cups of wine, he should make sure that he has a cup that holds exactly a reviis so that he will need to drink only slightly more than half a reviis.62 For the fourth cup, he should either drink enough wine to be able to recite a brochah acharonah himself or have someone be motzei him.63
It is preferable to drink the majority of the reviis at one time.64 If a person cannot do so, he should at least drink the majority of the reviis65 within kedei shtias reviis, which is approximately half a minute.66
Rav Heinemann, shli”ta, is of the opinion that the resulting mixture should contain at least 4% alcohol.69 Therefore, wine which has 12% alcohol content can be diluted into ⅓ wine and ⅔ grape juice. Alternatively, the wine can be diluted with water. Wine which has 12% alcohol content can be diluted into ⅓ wine and ⅔ water; alternatively, it can be diluted into ⅓ wine, ⅓ grape juice, and ⅓ water.70 If a person cannot drink wine, then he can use grape juice for the four cups.71 Some people may have difficulty tolerating both wine and grape juice. A person who will become incapacitated is not obligated to drink the arba kosos.72
Red wine should be used for the Seder.73 Throughout the year, it is preferable not to use cooked wine for Kiddush; the same is true for the Seder74. This is because uncooked wine tastes better than cooked wine. 75 It is debatable as to whether pasteurized wine has the same status as cooked wine in this regard.76
A child who has reached the age of chinuch, about five or six years old,77 should also be given arba kosos to drink;78 however, it is not essential to do so.79 A child does not need to drink a full reviis of wine or grape juice and should instead drink meloh lugmav, the amount of wine he can hold in his cheeks.80 It is customary to give arba kosos even to younger children, although they can be given a minimal amount of grape juice.81
When drinking the first cup, a person should have in mind that he is fulfilling the obligations of both Kiddush and the first of the arba kosos.82
A man should drink the arba kosos while leaning to his left side.83 If he did not lean while drinking the first, third or fourth kos he should not drink that kos a second time.84 If he did not lean while drinking the second kos, he should drink another kos during the meal while leaning to his left side.85
The matzos being used for the mitzvah should be Shemurah matzos. This is matzah that has been watched since the harvesting of the wheat to ensure that nothing has occurred which might cause it to become chometz.88 Many people have the custom to use only hand-baked matzos for this mitzvah; others use machine matzos.89
A person must eat one kezayis of matzah at the Seder.90 The Steipler Gaon91 and Rav Dovid Feinstein92 write that ideally one should eat ⅔ of a machine matzah or the equivalent volume of hand-baked matzah, which would be approximately half of a Tzelem Pupa hand matzah.93 However, upon experimentation, Rav Heinemann, shli”ta, found that half of a machine matzah or ⅓ of a Tzelem Pupa hand matzah contains the volume of matzah necessary for a kezayis.94
A person who has difficulty chewing may crush the kezayis of matzah before eating it.95 If necessary, he may also soak the matzah in water to facilitate eating the kezayis.96 A person who is unable to eat or drink the prescribed amount of matzah, marror or wine should consult his rav. Please refer to the article, “Pesach Guide For Those With Diabetes” for more information.
The kezayis of matzah should be eaten within the time span of kedei achilas pras.97 The kezayis should preferably be eaten within two minutes.98 If this cannot be done, it should at least be eaten within three99 or four minutes.100 A man should eat the matzah while leaning on his left side.101 If he did not do so, he should eat another kezayis without another brochah while leaning to his left side.102
After everyone at the Seder has finished washing netilas yadayim and returned to the table, the leader of the Seder should take the three matzos in front of him and recite the brochah of Hamotzi. The top and bottom matzos, which are both whole, will serve as the lechem mishnah.103 If feasible, he should then set down the bottom matzah and recite the brochah of Al Achilas Matzah while holding the top and broken middle matzos.104 He should then give each person at the Seder a kezayis, including within the kezayis some of the top and middle matzos over which the brochah has been made.105
A person should preferably chew the matzah without swallowing, until he has a kezayis of matzah in his mouth, and then swallow the kezayis at one time.106 In regards to this, one may rely upon the more lenient measurements of a kezayis, which calculate it as being less than ¼ of a machine matzah.107
People who find it impractical to swallow an entire kezayis at one time should instead eat the kezayis in the normal manner, which includes some of the top and broken middle matzos over which the brochah has been made.108
The Shulchan Aruch brings an opinion that one should eat a kezayis from the top matzah followed by a second kezayis from the broken middle matzah.109 However, a person who fulfills the requirement of eating a kezayis by eating the size of half of a machine matzah is actually eating two, when calculated according to the more lenient measurements of a kezayis.110 It is, therefore, sufficient to eat the size of half of a machine matzah in order to comply with the opinion that suggests eating two kezaysim.111
Before eating, a person should have in mind that he is about to perform the mitzvah of eating matzah.112 When reciting or hearing the brochah of Al Achilas Matzah, he should also have in mind the eating of the Afikoman.113
Nowadays, in the absence of the Korban Pesach, it is no longer a Torah requirement to eat marror at the Seder; however, there is a rabbinic obligation to do so.114 This obligation applies equally to men and women.115
Children who have reached the age of chinuch should also be given marror to eat, just like an adult.116
A person may use romaine lettuce for the marror,117 although it must be checked before Pesach to ensure that it does not harbor insects.118 He may use either the leaves or the lettuce stalks for marror.119 The lettuce does not need to be bitter,120 although there is an opinion that the lettuce must have some element of bitter taste.121 Some people have the custom not to use lettuce for marror.122
Raw horseradish may also be used for marror.123 It is customary that people who use lettuce for marror put some horseradish on the lettuce, although it is not necessary to do so.124 There is no need to use a lot of horseradish for this.125
The marror should be dipped into charoses, and the excess charoses shaken off.126 A person must eat a kezayis of marror.127 The amount of lettuce which will displace 25 cm³ of water would constitute a kezayis, according to Rav Chaim Noeh.128 This is equivalent to slightly less than 1 fl. oz. According to the Chazon Ish129 and Rav Dovid Feinstein,130 one should take 1.1 fl. oz. of lettuce for marror. Rav Heinemann, shli”ta, is of the opinion that a person should take 1 fl. oz. of lettuce.131 One large lettuce leaf or two large stalks displaces approximately 1 fl. oz. of water.132
The kezayis of marror should be eaten within the time span of kedei achilas pras.133 The kezayis should preferably be eaten within two minutes.134 If this cannot be done, it should at least be eaten within three135 or four minutes.136 One does not lean when eating the marror.137
The leader of the Seder should take the remaining bottom matzah and use it to give each person at the Seder a portion of korech.138 It is customary to prepare korech with two pieces of matzah sandwiching some marror.139 The marror should be dipped into charoses, and the excess charoses shaken off.140 Some have the custom not to dip the marror into charoses for korech.141
A person should eat one kezayis of matzah and one kezayis of marror for korech,142 and measure the kezayis of marror as described above.143 For the kezayis of matzah, it is sufficient to take half of the volume of matzah.144 Therefore, following the larger measurement as described above, one should eat ⅓ of a machine matzah or ¼ of a Tzelem Pupa hand matzah. Following the measurements of Rav Heinemann, shli”ta, it is sufficient to take ¼ of a machine matzah or 1/6 of a Tzelem Pupa hand matzah.145
Before eating korech, one should recite the paragraph Zecher L’Mikdash K’Hillel.146 Some suggest saying this paragraph after one has started to eat korech.147 A man should consume korech while leaning to his left side;148 if he did not do so, he does not need to eat another portion.149 From the time a person recites the brochah over the matzah until he eats the korech portion, it is preferable not to discuss matters unrelated to the eating of the matzah, marror, korech and the Seder meal.150
The leader of the Seder should give each person at the Seder a kezayis of matzah,151 including within the kezayis some of the remaining half of the middle matzah.152 Ideally, he should take the same volume of matzah as was used for the initial eating of matzah at the Seder.153
A man should eat the Afikoman while leaning to his left side.154 If he did not lean and has not started Birchas Hamazon, he should eat the Afikoman a second time, providing that it is not too difficult for him to do so.155 If he has started Birchas Hamazon, he should not wash and eat the Afikoman again.156
Chazal debate as to whether the Afikoman may be eaten all night long or by chatzos, halachic midnight. In order to fulfill both opinions, one must be careful to eat the Afikoman before chatzos.157 After eating the Afikoman, one may not consume other food.158
Rav Moshe Feinstein, zt”l, states that according to both opinions of chazal a person may not eat other food for the duration of the night.159 He also may not drink wine or fruit juice, with the exception of the remaining two cups of the arba kosos;160 he may drink water161 or tea162.
It has been argued that, according to the opinion that the Afikoman must be eaten by chatzos, the prohibition against consuming additional food also ends at chatzos.163 If so, when chatzos is approaching and a person has not yet finished his meal, he may eat a kezayis of matzah and verbally state the following: If the correct opinion is that one may eat the Afikoman until chatzos, then this matzah should be regarded as the Afikoman; however, if one has all night to eat the Afikoman, then it should not be regarded as such. He may eat the matzah, wait until chatzos, and then continue his meal. After the meal, he should eat another kezayis of matzah and state the following: If the correct opinion is that one has all night to eat the Afikoman, then this matzah should be regarded as the Afikoman; but, if the Afikoman must be eaten before chatzos, then it should not be regarded as such.164 However, Rav Moshe Feinstein, zt”l, rejects this position and states that the Afikoman must simply be eaten before chatzos.165
When Moshiach comes, and the Beis Hamikdash is rebuilt, we will once again offer the Korban Pesach in accordance with the Torah obligation to eat the Korban Pesach with matzah and marror.166 Bimehera Yiboneh Hamikdash.

M.B. states that for Kiddush one should, lechatchilah, consider a reviis as equivalent to the volume of two present day eggs.

He further states that he discussed the issue with Rav Dovid Feinstein, who agreed that this was a more accurate measurement. Rav Heinemann shli”ta measured a present day egg as having the volume of 1.9 fl. oz. The volume of two eggs would therefore equal 3.8 fl. oz.

63. M.B. 472:30.
64. M.B. 472:34 writes that ideally the rov reviis should be drunk at one time. Kol Dodi explains this to means that the rov reviis should be drunk without taking the cup from one’s mouth. See also his rebuttal of Machatzis Hashekel 472:1.

70. See M.B. 204:32; M.B. 272:16, that wine can be diluted one part in six and still retain the brocha of Borei Pri Hagofen. See Machaztis Hashekel 204:16 quoting Eliyahu Rabba; Pri Megadim siman 204 aishhel avrohom 16; Kol Dodi. The wine used for the arba kosos should not be diluted to this extent because such a mixture would be only minimally alcoholic. Hilchos Chag Bechag (Chag HaPesach), page 422, states that it is customary to dilute ⅓ wine with ⅔ grape juice. Rav Heinemann shli”ta is of the opinion that the mixture should retain a 4% alcohol content.
71. M.B. 472:37. Teshuvos VeHanhogos 2:243 states that a sick person or old person may lechatchilah use grape juice for arba kosos and notes that the Chebiner Rav and the Brisker Rav did so. See also Shulchan Aruch HaGraz 472:17; Hilchos Chag Bechag page 415; Halichos Shlomo Pesach 9:11. Concerning the dilution of grape juice, see Minchas Shlomo 1:4; Vezos Habracha page 116 and Hilchos Shabbas BeShabbas page 386 quoting Rav Elyashiv shli”ta . According to their viewpoint, grape juice which is used for arba kosos should not be mixed with more than a little amount of water.

76. The laws of stam yayin do not apply to cooked wine. Igros Moshe, Yoreh Deah 2:52 and Yoreh Deah 3:31, states that they similarly do not apply to pasteurized wine. However Minchas Shlomo 1:25 and Rav Elyashiv shli”ta , Kovetz Teshuvos 1:75, disagree. It is not clear whether the Igros Moshe would also treat pasteurized wine as cooked wine with regard to Kiddush. The Meiri, Bava Basra 97, is of the opinion that cooked wine should not be used for Kiddush even if the cooking did not result in any taste change. Presumably, the Meiri would consider pasteurized wine as being in this category.

Rav Shlomo Kluger paskened that matza made by a hand powered machine is not acceptable for the Mitzva; whereas Rav Yosef Shaul Natansohn (author of Teshuvos Shoel U’meishiv) was lenient, as recorded in Sdei Chemed vol. 7 page 397. Concerning matza made by an electric machine, the Maharsham 4:129, 9:31 was stringent and the Divrei Malkiel 4:20 was lenient. See also Chazon Ish, Orach Chaim 6:10; Hilchos Chag Bechag page 337.
90. Rambam, Hilchos Chometz U’matza 6:1.
91. M.B. 486:1 implies that one should eat the amount of matza which has the same volume as a present day egg. Shiurin Shel Torah, page 65 and footnote on page 66, states that in order to meet this requirement, it is appropriate to ensure that the first kezayis be approximately the size of ⅔ of a machine matza.
92. Rav Dovid Feinstein shli”ta , Kol Dodi, writes that the matza which is eaten for the kezayis should have the volume of 1.5 fl. oz. Sefer Kezayis Hashalem, page 91, states that this is equivalent to the size of ⅔ of a machine matza. Kol Dodi further states that this measurement is given for the first night of Pesach, but on the second night of Pesach one can be more lenient.
93. Heard from Rav Heinemann shli”ta .
94. Heard from Rav Heinemann shli”ta . Orchos Rabbeinu vol. 2 page 66 writes that the Steipler Gaon noted that the Chazon Ish would take ¼ of a hand baked matza as a kezayis for both Achilas matza and korech, and eat additional matza during the meal while leaning so as to fulfill the Mitzva without any doubt. See further Orchos Rabbeinu ibid.
95. B.H. 461:4 ‘yotzei’.
96. See M.B. 461:17-18; S.H.461:32. M.B. 458:4 states that there are scrupulous people who are stringent and do not let matza become wet for the duration of Pesach, due to the concern that there might be some residual flour below the surface of the matza which could become chometz upon contact with water. This is the custom of not eating gebrochts. See further Shaarei Teshuvah 460:1.

105. S.A. 475:1; M.B.475:2; M.B. 475:6; M.B. 475:8. Piskei Tesuvos 475:2 describes an alternative custom for the recitation of the brachos and division of the matza. The leader of the Seder makes the brocha of Hamotzi and then divides the kezayis of matza for each person at the Seder. He includes within the kezayis some of the matza over which he made the brocha. Each individual then recites the brocha of Al Achilas Matza.
106. M.B. 475:9.
107. Shiurin Shel Torah siman 11 states that fundamentally the Chazon Ish paskened in accordance with Rav Chaim of Volozhin who stated that a kezayis is measured as the average size of a present day olive, which at a maximum would be the volume of ⅓ of a present day egg. Based on his statement that ⅔ of a machine matza contains the volume of a present day egg, 2/9 of a machine matza would contain the volume of a kezayis. See also sefer Kezayis Hasholem, page 24; Orchos Rabbeinu vol. 2 pages 66-69.
108. See S.A. 475:1. Orchos Rabbeinu vol. 2 page 70 quotes Rav Chaim Kanievsky shli”ta as stating that the Chazon Ish did not put a whole kezayis of matza in his mouth at one time, but ate it in the normal manner within three minutes. Orchos Rabbeinu vol. 2 page 66 similarly quotes the Steipler Gaon as saying that one should eat the matza in the normal manner. See also Halichos Shlomo Pesach 9:41 and Halichos Shlomo Tefillah page 380, quoting Rav Shlomo Zalman Auerbach.
109. See S.A. 475:1; M.B. 475:9; Orchos Rabbeinu vol. 2 page 69. B.H. 475:1 ‘kezayis’ questions the necessity of eating two kezaysim and quotes sources to the contrary. Orchos Rabbeinu vol. 2 pages 69-70 quotes Rav Chaim Kanievsky shli”ta as stating that the Chazon Ish told him that the Halacha follows the opinion that it is necessary to eat only one kezayis.
110. As stated above, fundamentally the Chazon Ish paskened that a kezayis is measured as the volume of a present day olive, which is smaller than the volume of ¼ of a machine matza.

128. M.B. 486:1 states that with regard to marror, which is nowadays a rabbinic obligation, one can measure a kezayis as being the size of half of a present day egg. Rav Chaim Noeh, Shiurei Torah page 191, states that half a present day egg has a volume of 28.8 cm³. 28.8 cm³ = 0.97 fl. oz.
129. Chazon Ish, Orach Chaim 100 and 39:17, states that with regard to marror one can measure a kezayis as being equivalent to the volume of ⅔ of a present day egg. Shiurin Shel Torah page 65 states that a present day egg has a volume of 50cm³. Therefore, a kezayis will have a volume of 33.3 cm³. 33.3 cm³ = 1.13 fl. oz. Shiurin Shel Torah siman 11 states that fundamentally the Chazon Ish paskened in accordance with Rav Chaim of Volozhin that a kezayis is measured as the size of a present day olive, which at a maximum would have the volume of ⅓ of a present day egg. He also states that a person who has difficulty eating marror can rely upon this measurement, which calculates as 17cm³ or 0.58 fl. oz. Also see the letter written by the Steipler Gaon, which is reproduced at the end of the sefer Hilchos Chag BeChag.

However, M.B. 477:1 states that for afikoman one should ideally eat two kezaysim of matza. Two kezaysim following the smaller measurement of a kezayis is equivalent to one kezayis of the larger measurement. Furthermore, S.H. 477:4 states that the afikoman is the primary matzos mitzva according to Rashi and the Rashbam; Kol Dodi states that this is a further reason to take a volume of matza consistent with the larger measurement of a kezayis.
