Are you looking for something different, yet not too difficult to wow your friends at dinner? Well, here it is. Shrimp may be substituted. Crawfish Zerpa was the grand prize winner in the 1986 Times-Picayune Cooking Contest, created by Jacqueline S. Keller. This is a very rich and absolutely FABULOUS dish, crying out to be served at your next dinner party. It's not called for in the recipe but I like to add chopped green onions and fresh parsley just before serving. Serve with a big green salad tossed with a simple herb vinaigrette, and hot French bread and perhaps a nice Beaujolais. Bon Appetit, y'all!
