Sauce béchamel


Bechamel sauce is a very common sauce in French cooking. It’s quite easy to prepare and require very few limited ingredients: milk, butter, wheat flour, nutmeg… Anyway, it requires attention otherwised the sauce can burn or get lumps.

That bechamel sauce is used in different recipes: Croque-Monsieur (grilled cheese sandwich), gratins, lasagna, stuffed vegetables, savoury tarts…

Another version of that sauce exist without milk. In that case we call it: “sauce blanche” and we use another liquid: in general it’s water, broth, cooking water of mussels, fish fumet, veal stock…
