It is
Corn and Crab Soup Day. That combination has been around in Chinese restaurants for who knows how long, in the usual thin style common to most Asian soups. But that's not the soup the name conjures up around New Orleans. A rich, spicy potage came to light during Paul Prudhomme's tour of duty as chef at Commander's Palace, in the late 1970s. That soup had the two namesake ingredients in a matrix of reduced heavy cream and crab stock, with a good shake of cayenne pepper to make it convincing.
What makes a corn and crab soup great is the size of the crab lumps, the richness of the broth, and the freshness of the corn. The best versions involve corn cut freshly off the cob, with the corn milk collected and added to the broth. Sometimes a stock is even made from the corn cobs, and that's good, too. It's really simple to make--if you have any instincts at all, you already know how to make it from just what I've already told you here.Corn and crab soup (also called bisque by some purveyors) quickly became part of the pantheon of classic New Orleans soups, right up there with gumbo, turtle soup, and oyster-artichoke. Some restaurants have become famous for it, notably Vincent's (where they serve it in a bowl made of French bread), most of the Brennan restaurants, and even Copeland's.
