More on "ho'il" - how the Gemara line up the rabbis in trying to understand how far this logic can apply. Working through the tannaitic sources to figure out the rationale. Also: How do you bake bread (or matzah) with regard to the mitzvah of challah? One family separates its dough in small amounts that don't require challah to be taken - but also speed up the process, and sidesteps the worry of chametz. But what happens to the mitzvah of taking challah? A discussion of whether the portions can combine together to form the amount that requires the taking of challah. Perhaps that combining only works if the rolls of bread themselves touch while baking - what about long rolls that don't touch? What about them being baked together? Well, the Gemara has a new case of women baking their matzot in turns (or are they an assembly line?). How many different variables will have impact on those loaves? Differences in psak between R. Eliezer and R. Akiva, given life experiences. Also: At what point does leavening happen? In physical symptoms, not on a clock (which they didn't have, anyway). The mishnah presents descriptions of the progress in baking to chametz, and when the punishment of karet kicks in.
