I found this thread while searching on "clam". I have never seen frozen shellfish in the shell except for mussels. How are they? Mussels seem to be hit or miss when I order them out and now I think the misses were of the frozen variety.
I'm dying for fresh clams and have a 2 lb bag on hold for pickup this weekend. They're pretty hard to get hold of this far inland. My local (60 mile drive each way) seafood purveyor heads for the gulf coast every Monday and comes back to open Thursday-Saturday. If I don't call within 30 minutes of opening Thursday, I don't get any clams, assuming he even found any. I guess Cedar Key is too far down the coast for him and he picks them up somewhere on the panhandle from a wholesaler.
Anyway, if I can find these frozen clams somewhere I will be sure to try them and report back. Linguine with clam sauce and lots of garlic. Mmmmmmm.
