Shells of Fat-liver, with Mushrooms

Ingredients

Directions

Prepare the filling

Cut the fat-liver into small dice.
Combine the fat-liver and diced mushrooms in a stewpan, season with salt and pepper, and cover.
In a separate flat stewpan, heat the béchamel sauce, stirring, and gradually add the melted glaze until the sauce is succulent but not too thick.
Mix the salpicon (fat-liver and mushrooms) into the béchamel sauce and warm without boiling.

Fill and brown

Fill ten table-shells with the mixture, smooth the tops, sprinkle with bread crumbs, and salamander (broil) until golden.
Serve the shells on a folded napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Fat-liver: Provides the rich, soft body and savoury flavour of the filling.
Cooked mushrooms: Add earthy flavour and a tender, moist texture to the filling.
Béchamel sauce: Binds the chopped pieces together into a creamy, spoonable filling.
Melted glaze: Adds concentrated savoury richness and body to the sauce.
Bread crumbs: Form a crisp, golden topping when browned under heat.

The step that matters

Warm the filling without boiling. Boiling a starch-thickened béchamel can cause it to break or turn grainy and thick, and overheating fat-liver can make it tough and dry. Gentle heat keeps the sauce smooth and the filling tender.
