Halachos of K'Zayis
Ever wonder how many pretzels you have to eat in order to say a brachah achrona - a blessing recited after having eaten? This small but useful book has life-size, color photos and explanations to help you easily and accurately determine the amount of each food you need to eat in order to make a blessing after eating.
