Certainly a cracker's worth. And it's easy to understand how and why alternate views developed.

Assuming, of course, that you hold that way. The Rambam didn't; he translated everything into weight. Many communities (mostly Sefaradi) followed in his footsteps, right up to Rav Mordechai Eliyahu and others in our time. Oddly, you listed a weight here in this post (29 g). If you want to be consistent with your assertion, then you should have given a volume or area; just like the folks who use those placards on erev Pesah to figure out their measures. We just use weights, as the Rambam taught.Mordechai Y. Scherhttps://www.blogger.com/profile/06774262478551329181noreply@blogger.com
