Imports of whole frozen Chinese crawfish have been here for about 10 or 12 years now, and more recently from Spain. The quality of these are often poor due to inconsistent seasoning and cooking times and due to long frozen storage times. Louisiana crawfish processors are beginning to sell more whole frozen crawfish packaged in seasoning, and although I have not tried them yet, I understand they are quite good. These are fully cooked and require only heating –– some packages can be heated in a microwave. I believe most of these are sold to resturants and perhaps more locally (LA, TX, TN, MS, etc.) but may appear more and more in retail outlets. The processors are increasing the quantity of these products each year and they should become more available. Of course these probably will never be as good as fresh boiled product –– when done right –– but it does provide a means of increasing the seasonal supply and makes for easy preparation for those not geared up for the traditional boil.
