The best thing to find inside a chocolate is some type of nougat and nuts. My absolute favorite is caramel and pecans- a turtle– After that, walnuts with nougat. Can anyone resist a chocolate covered cherry? Nope, didn't think so.
Now, the fastest one I'll spit out is one with coconut inside. Not a fan of chocolate with coconut. At all. I like chocolate and I like coconut but do not cross the line and combine them. I also don't like the ones with that icky jelly like substance in them.
Call me nuts, but give me nuts- every time!
