Seafood Chawder Soup & Lobster Thermadore

Lobster Thermidor is a French dish consisting of a creamy cheesy mixture of cooked lobster meat, egg yolks, and brandy or sherry, stuffed into a lobster shell, and optionally served with an oven-browned cheese crust. The sauce must contain mustard (typically powdered mustard) in order to be true to the original recipe and to have the distinctive Thermidor taste.
