Wasting food is never a good idea, and when we prepare dishes with shrimp, crab or crayfish, we know a bisque will be made with the shells. Unless it is the shedding phase, crayfish shells are usually hard and crushing them during cooking will bring out flavours.
Fish and seafood are sold alive on local markets in China which is not always the case in other parts of the world. If you are lucky to find live produce, it is necessary to clean and brush the crayfish under cold running water. Once they are clean, cook them immediately.
This crayfish bisque recipe is suitable for after you have prepared recipes in which the crayfish tails were used. We have used a few fresh crayfish for the garnish of this bisque and as our recipe was made from scratch, we will be sure to use the remaining crayfish for other recipes and you can also do the same.
