I just bought and steamed 18 littleneck clams in half a beer and ate them for dinner. They were delicious. (And I'd've eaten them raw, but those suckers are hard to open!)
Now, my question: Are their empty shells good for anything? Namely, making stock? I've never made clam stock and don't really know if it's even a thing. Also, the shells have already been steamed for five minutes or so to open the clams, and they contain no meat except that tiny connective muscle.
I'm planning to make corn and clam chowder in the next few days from canned clams and frozen corn. I have a bunch of kernelless corn cobs in the freezer that I was gonna turn into stock for it, so I'd just add the clam shells if y'all think they'd do anything. If the shells would impart enough flavor, I'd skip the addition of clam juice to the chowder.
