Question:
Hi Rabbi,
If I were to eat a certain amount of food that would require borei nefashos if a kezayis was eaten, but I am unsure that I really did eat enough, can I have a bit of a drink like orange juice or soda to obligate it? If I am really only drinking for this purpose, would I even make a bracha?
Thank you
Answer:
Hello,
Drinking orange juice or flavored soda would require a bracha rishona, because you benefited from the taste of the drink. In order to make the bracha achrona you would need to drink a reviis, because food and drink do not combine with each other to make a shiur of a kzayis.
Best wishes
