I guess my ice cream tastes run toward the childish end of things; bubble gum (even though I don't like real bubble gum?!), cookie dough, blue moon...but I might like them mainly for nostalgic reasons, who knows. Anything with brownie chunks in it is the best thing one can possibly put in one's mouth, seriously.
There is this seasonal flavor from Dean's that I discovered during my last pregnancy, lemon ice-box pie, which is wholly and entirely responsible for any and all weight I gained, since I couldn't keep much else down
Kinds I don't like are ones with nuts, or fruit chunks in it. Not a big fan of things with extreme texture differences being combined together.
