What each ingredient does

Blanched throat sweetbread
Forms the main body of the filling, giving it a tender, delicate bite.
Good béchamel sauce
Binds the diced ingredients together and adds a creamy, moist texture.
Mushrooms
Add moisture and earthy flavour that complements the sweetbread.
Truffle
Contributes a strong, aromatic earthy flavour that defines the dish.
Crawfish-butter
Adds rich, savoury flavour and colour to the finished mixture.

The step that matters

Gently tossing while cooking on low heat. Sweetbread is delicate and can toughen or break apart under high heat or rough stirring. Low heat and gentle tossing keep the pieces tender while the béchamel thickens evenly around them.
