A GENTLE SAUTÉ OF FRESH FISH
Serves 4 and halves or doubles easily.
This cooking technique succeeds with any small whole fish or fillet. With delicately flavored fish such as northern pike and walleye, keep improvised seasonings gentle. With fuller-flavored fish such as sunfish and trout, flavors could be bolder.
2 to 21/2 lb. whole fish, or 11/2 lb. fillets
Salt and freshly ground black pepper, to taste
3 to 4 tbsp. butter or extra-virgin olive oil
1 large garlic clove, thinly sliced
1/4 medium onion, cut into 1/4-in. dice
