Why have a crawfish boil? If you have never been to a crawfish boil, you don't know what you are missing. This is the best possible way to eat crawfish. They cook up wonderfully in the boiler, and when they come out they will be somewhat spicy. You can always spice it up more with some (a lot) hot sauce if it is not hot enough for you.
Invite your entire family, invite your friends, invite the whole neighborhood to share in the good food you are boiling up if you can!
