re: 1st time boiling crawfish!

1 large bag of Louisiana crawfish boil powder.
1 bottle Louisiana liquid crawfish boil.
Bring water to a boil and add seasonings.
Add potatoes when water is boiling and cook for 10-15 minutes.
Put crawfish in Basket with the potatoes and bring back to boil.
Once boiling cook 2 minutes then kill the fire.
Add corn to soak.
Soak 30-45 minutes.

That is the most basic way in my opinion. You can add whatever else you would like as far as vegetables and meats go. I personally don't like adding ice because it dilutes the water.
