Crawfish in Garlic Butter

1. Unless you bought them prepurged, the crawfish will have to be soaked in an ice chest full of fresh water for about 10 minutes before cooking, to clean their exterior and cause them to spit up the swampy muck in their intestines.
2. Fill a pot (fitted with a strainer insert) halfway with water and bring to a boil over high heat. Add hot sauce, salt and cayenne pepper.
3. Add potatoes and onions to the pot. Boil vegetables for about 10 minutes.
4. Add crawfish to the pot. After 5 minutes turn off the heat, cover, and let the crawfish steep to absorb the flavors for 15 to 20 minutes.
5. In skillet melt butter over low heat. Saute minced garlic and green onion until tender.
6. Arrange crawfish and butter in single layer in skillet, saute 1 minute.
