A 3.5 oz. chocolate patty is the Peterson's Candy version of a candy bar.
The kitchen sink is a mixture of pecans, peanuts, almonds, cashews, coconut, raisins as well as milk, dark, and white chocolate. Literally, a little everything just like a 'kitchen sink'.
The peanut Patty is similar to a peanut cluster, but in the form of a Patty... and with a little more chocolate.
