One of the best ones we've made is a mascarpone ice cream. Also, strawberry-basil sorbet.
Edit: Sorry, just realized - do you mean to make, or to buy? if to buy, man.....ice cream is a downfall for us. Too many to list, but they all have "texture" in common - e.g., less fond of straight chocolate, etc., but chocolate with chocolate coffee beans, chunks of fudge, etc. Will say, always craved cherry with chocolate anything. Orange and chocolate is another great combo.
