Be sure to wash the clams very, very well, to remove any grit. There’s nothing worse than biting into a grain of sand when eating chowder. So give the clams a good scrubbing with a stiff brush under cold running water. I used Littleneck clams (about 3 dozen for this recipe) whose meat is about the size of a silver dollar, so I ran a chef’s knife over them after they’re cooked – but don’t overdo it. You want distinct, large pieces of clams. Not tiny bits that no one know what they are. If using other clams that are smaller, you might not need or want to chop them. See note at end of recipe for using canned clams.
Some versions use all whole milk, others use heavy cream. I like about one-third cream, but you can use all whole milk or all
half-and-half. Skim or low-fat milk isn’t recommended. Whatever you use, Just be sure not to let the chowder boil once you’ve added the milk to it, or it can break.
For best results, let the chowder cool and refrigerate it for a few hours – I let mine sit 8 hours, to allow it to thicken. Rewarm it gently before serving. Be sure to serve with oyster crackers which people can float them on top. Crumbled saltines will work in a pinch. (Or make your own oyster crackers with the recipe at the end of this post.)
