Topic

Baking מצה on פסח: combining small batches for חלה, preventing dough from becoming חמץ, and the stages of leavening (שיאור and סידוק).

Overview

The amud opens by finishing a question on רב: the גמרא explains that his 'קב' is the larger Melogna קב, which equals the חלה amount. רב יוסף reports that his household bakes מצה in small batches on פסח, and אביי objects that this stringency causes חלה to be lost. רב יוסף answers with רבי אליעזר's rule that a basket combines loaves for חלה, and the two argue over whether this applies even to separate loaves. רבי ירמיה asks whether a flat board with no rim also combines loaves, and the question ends with תיקו. A new משנה then gives three views on how three women may knead and bake מצה together without the dough becoming חמץ. A ברייתא explains the חכמים's rotation, and רבי עקיבא recalls asking רבן גמליאל about it. רבן גמליאל answered with one rule: if the dough rises, cool it with cold water. A final משנה defines the stages of rising, שיאור and סידוק. The גמרא sorts out the views of רבי יהודה and רבי מאיר, and רבא explains רבי מאיר's reason.
