Keeping Food Hot on Shabbat: The Laws of Insulation
Rabbi Chay Amar
What may you use to keep food warm on Shabbat, and when does insulation become prohibited? This practical class explores the Rambam’s laws of hatmanah, the rabbinic safeguards surrounding heat-preserving and heat-increasing materials, and their modern applications. Learn when a hot pot may be covered, when a covering may be replaced, how transferring food to another vessel changes the law, and practical principles for preparing hot tea on Shabbat.
