Onion

Roasting time at 325°F: 2 hours for medium rare—internal temperature 125° to 130°F (about 15 minutes per pound).

Traditional chowders all start off with a hearty soup base of onions and potatoes, and that makes a good soup just by itself. To this fragrant base you then add chunks of fish, or clams, or corn, or whatever else seems appropriate.

This is a bare-bones recipe for the simple all-purpose vinaigrette, which you will vary as you wish; you’ll find suggestions at the end of this recipe. Its beauty lies solely in the quality of your ingredients. Note that you will so often see proportions of 1 part vinegar to 3 parts oil, but that can make a very acid, very vinegary vinaigrette. I use the proportions of a very dry martini, since you can always add more vinegar or lemon but you can’t take it out.

(Can be prepared ahead of time.)
