Close as I can tell, this recipe should make something very similar to the delightful winning finger-food called the Cajun Pistol at the Gulf Shores National Shrimp Festival.
1/2 cup chopped onion
1/2 cup chopped celery
1/2 cup butter
Salt and pepper
1 pound crawfish tails
1/4 cup shredded Cheddar cheese
1/4 cup shredded Swiss cheese or whatever
cheese you like
1 1/2 tablespoons chopped green onion
1 1/2 tablespoons chopped parsley
Shake or two of ground hot pepper
2 cups Bisquick
3/4 cup water
Vegetable oil for frying
Yield: about 16 beignets
May be frozen before frying. Thaw for 10 minutes and fry as usual.
