Ask the Rabbi

STAR-K CERTIFICATIONrealizes that there is no substitute for a person's own Rav. However, in today's busy and connected world many people have difficulty getting in touch with their Rabbanim when they are needed. In an effort to offer a solution to this challenge, STAR-K launched its Institute of Halachah as a public service. Over the years, the agency's Kashrus Hotline has answered more and more halachic questions beyond the scope of Kashrus information, from consumers the world over, beyond the standard steady stream of inquiries regarding the kosher status of foods and certified Sabbath mode appliances which has made the STAR-K Kosher Hotline famous. The formation of a separate official division within STAR-K testifies to the need for addressing these issues.

The Institute of Halachah is directed by HaRav Mordechai Frankel, under the guidance of HaRav Moshe Heinemann, STAR-K's Rabbinic Administrator. It is an invaluable resource for a diverse array of rabbis to discuss general halachic matters, as well as gain access to source materials for shiurim and answers to congregants' questions.

Shailos may emailed using the form below, or called into the Institute of Halacha at 410-484-4110 x238. Rabbi Frankel or on occasion another STAR-K Rabbi will respond to your email or return your call if you leave a message and phone number.

  • Halacha Questions

  • Are ramen noodles (e.g. Tradition soup) allowed to be cooked on Shabbos? Are they already cooked, and can we apply the rule of ein bishul achar bishul? How about cooking them in a kli sheini or kli shlishi?
  • Halacha Questions

  • In cases where amira le’akum is permitted on Shabbos, would it be permitted to ask Alexa to do it? For example, could you ask Alexa to turn on an air conditioner on Shabbos, if the heat is making you feel sick?
  • Halacha Questions

  • I daven in a small minyan during the week. The ba’al tefillah regularly begins chazaras hashatz when only six others have finished. Is that a problem? If I leave the minyan because of this, it may cause them not to have a minyan on some days.
  • Halacha Questions

  • We generally cook food on Friday and then transfer it to the oven just before Shabbos starts, with the oven set to turn off at the beginning of the meal. My son-in-law questioned that. Is there any problem with this?
