Is it an obligation to bake challah at home?

The poskim record a custom to knead and bake challah at home each erev Shabbos rather than buy bread from the market as on other days, and the Rama writes not to deviate from this minhag.¹ Several reasons are given for this custom:

(1) Kneading the dough lets one be mafrish challah, helping to atone for chet etz hadaas, which ruined the “challah” of the world (Adam who was kneaded and taken from the earth);² (2) the very act of baking at home, rather than buying from the market, is in itself an honor for Shabbos;³ (3) it ensures one has pas Yisroel for Shabbos rather than pas palter (which was often relied upon in various situations).⁴

From the Alter Rebbe’s wording, it appears that all three reasons are important. One should therefore bake challah at home even when pas Yisroel is available, and separate the shiur challah when finished. He notes that this be done specifically on erev Shabbos, much as one prepares for Shabbos by bathing and cutting nails, so it’s noticeably l’kavod Shabbos.⁵

Contemporary poskim debate whether it is better to bake a smaller batch fresh every week or to knead one full shiur challah, take challah with a bracha, and freeze the rest to reheat as needed. A middle path is to freeze the larger batch of dough and bake it fresh each erev Shabbos, achieving the fresh taste and the erev Shabbos baking. But if the taste of frozen challah is comparable to freshly baked ones, one may bake once every several weeks and just reheat weekly.⁶

Today, when bakeries produce tasty challos made especially for Shabbos, some poskim say that they satisfy kavod Shabbos, especially given current-day pressures and responsibilities. Still, baking challa at home is definitely praiseworthy.⁷
