Knowing what blessings and after-blessings to make on foods is important, but it's also imperative to know how much food must be eaten in order to qualify for an afterblessing. Now, the complex and little-known topic of k'zayis (literally 'like an olive'--indicating the portion size that qualifies for an afterblessing) has become crystal clear and couldn't be easier to follow. This unique book shows full-size, color pictures of the most commonly eaten foods, indicating how much must be eaten in order to fulfill a shiur k'zayis. Includes modern snack foods, breads, and an entire section on k'zaysim on Pesach, and the formulas for calculating shiur k'zayis in foods of different shapes.

    This book has pictures of 100s of kinds of food and tells you the K'zayis. It also tells you how to figure out the K'zait of foods that aren't shown in the book (although almost all foods are). Overall, this is a great book. I have other books by this author and all of them are great. Well organized and very clear.
