OK, its getting near the season for clambakes. I have made clam chowder several times in past seasons using the broth from fresh clams steamed in some wine and herbs. The problem is this ALWAYS comes out way too salty. So much so in fact that the final chowder winds up being still a bit on the salty side even though I don't add any more. Are there any suggestions on what I can do to get the good clam flavour sans the salt?
