Flash-frying squid in deep-oil is one of the best squid-cooking methods. Once upon a time, fried squid could only be found in Little Italy-style-red-sauce joints -- and they didn't spare the red sauce! Today, all kinds of chefs across the country love to present these crispy little morsels as a meal opener. And, happily, most people have discovered that the flavor and texture of the fried squid are ruined by a heavy blanket of sauce. The following simple recipe yields the crispiest squid you'll find. We like it with salt alone, maybe a little lemon. But if you crave a sauce, serve mayonnaise on the side. Serves 4 generously as a first course.
