Béchamel sauce
============== 2021-11-04


Comment: A basic sauce for many preparations. Typically butter, flour and milk, the liquid may, depending on the case, be a broth or a fish stock. The consistency of the sauce depends on the ratio of the relative amount of liquid, adjusted according to the need of the recipe. Typically, for 1 l of liquid, there are 70 g of butter and 70 g of flour. The amount of butter and flour is normally the same. In some cases, you can slightly favor butter, never flour. The Béchamel sauce will be more liquid for lasagna (which needs liquid for pasta), or thicker (for example for a soufflé).
The seasoning, is normally salt, pepper and nutmeg. Other elements are considered depending on the purpose of the sauce: bay leaf, thyme, garlic, capers, cayenne pepper and of course various cheeses.

Exemple, for 4 to 6 servings, sauce Mornay for raviolis : 30 g flour, 30 g butter, 5 dl milk, 150+ g cheese. A little more milk than usual because of the cheese.
