Q. If I made a mezonos brocho on a cracker with peanut butter and I have left some of the peanut butter on the knife I used and want to eat it the leftover by itself, do I have to make a shehakol?
What brocho do you make on chunky peanut butter, that has peanut lumps mixed in it?

A. Horav Shlomo Miller’s Shlit’a opinion is that you don’t have to recite a shehakol brocho on the reminder peanut butter since it was already included in the original mezonos brocho.
In regards to the brocho on chunky peanut butter the Rov’s opinion is that the shehakol brocho is maintained, and no haadama has to be recited, since it the majority of the product is the paste and not the solid peanut pieces.
