Béchamel sauce and its descendant Mornay sauce (béchamel with cheese) are the most traditional sauces for making gratins. Béchamel has the advantage of being lighter than heavy cream. It also can be made quite thick—thicker than heavy cream, which breaks if overreduced. I avoid béchamel in gratins made with ingredients that are already starchy, such as pasta and potatoes, but prefer it to cream for gratins made with most other vegetables because it’s less rich.

If you follow most recipes for béchamel you’ll end up with something very bland (not necessarily a bad thing, but a situation that is easily improved). Modern béchamel is made by adding milk to a simple roux, and at most flavoring it with a little nutmeg and cayenne. This wasn’t always the case. Escoffier’s recipe, now about 100 years old, contains onion, along with cubes of veal and a sprig of thyme, sweated in butter before the flour and milk are added. Some 70 years before Escoffier, Carême gives a recipe for béchamel made by adding a ham-enriched concentrated veal broth to a roux—producing what’s now called a sauce velouté—and then converting the velouté into béchamel by adding heavy cream. The resulting sauce is actually closer to what was later called a sauce suprême. About 80 years before Carême, Menon, in his Les Soupers de la Cour (1755), gives a recipe in which slices of raw ham, mushrooms, shallots, garlic, cloves, bay leaves, and basil are gently cooked in butter until colored (before the nineteenth century, béchamel sauce wasn’t a white sauce as it is today), flour is sprinkled over all, and the mixture moistened with cream. I’m not suggesting you go out and buy 10 pounds [4.5 kg] of veal to improve your béchamel sauce, but a few veal trimmings or bits of prosciutto end will work wonders. Here’s my own béchamel. If you don’t have some of the ingredients, leave them out—your sauce will still be a lot better than the standard version. If you’re in a mad rush, just make a roux with the butter and flour, skip the vegetables and prosciutto, and simmer, skim, and season as described on the following page.
