Bracha Acharona

what do you do if you forget to make a bracha acharona and 72 minutes has passed since you finished eating?
-- Rebecca Schenker
This is a very practical question! If 72 minutes have passed, Poskim suggest that lechatchilah, you should eat another food (or the same, if you have any left) that has the same bracha acharona, in that location, and then recite the bracha acharona. Bedieved, even if 72 minutes have passed and for whatever reason, you can't eat more food that has the same bracha acharona, you may make the bracha acharona as long as you have not begun to feel hungry yet.
