I like them raw, straight from the shell. I did grill them once with really fine shallots, Tabasco and herbs...very nice. I have some being delivered today.
Pasta - I think it's an acquired taste. When I first had them it was part of a seafood platter. Next time, years later, I was at my friends house and he did the finely chopped shallots and a dash of tobasco....then I started liking them.
