I tried the peanut butter one and all I can say is that I want the original one back. The center core has a funky flavor and texture and frankly, results in less actual ice cream that I'm getting.
These cores are pissing me off. They started stocking less regular Ben and Jerry's to make way for these, so now I have less flavor options. I did finally try the cotton candy and it's damn good.
Dammit, for the longest time I was trying to find a way to "swirl" things like dulce de leche and thick fudge into my homemade ice creams without getting them dissolved, and this method was one of the first lazy-ass things I tried. I should sue.
