This Recipe Makes 8 Thermidors

Crayfish Thermidor is a classic French preparation that was very popular in upscale restaurants during the early to mid-1920’s.

In the dish, the crayfish meat is combined into a rich heavy cream based sauce. The crayfish & sauce mixture is spooned back into the shells, topped with more cheese, & baked until golden brown.

Crayfish Thermidor is surprisingly simple to make & if Crayfish is not available then Lobster may be used instead.
