Rav David Brofsky Shiur #48: Berakha Acharona: Kedei Akhilat Peras – Foods and Liquids In the previous shiurim, we discussed the laws of the berakha acharona. We learned that one only says a berakha acharona (Al Ha-Michya, Borei Nefashot) after eating a ke-zayit of food, and we studied the size and measurement of a ke-zayit. In addition, the Posekim assume that one must eat the food within a certain time-frame, a shi’ur. This week, we will discuss the time in which one must eat a ke-zayit of food in order to become obligated to say a berakha acharona. In addition, we will discuss whether there are any differences between food and drink with regard to these questions. The Laws of Berakhot (Semester 3)
