Béchamel White Sauce with a Pale Roux and Nutmeg
A smooth French white sauce thickened with a pale roux and seasoned with nutmeg.
Béchamel is a smooth white sauce made by whisking milk into a butter-and-flour roux. The source’s suggestion to cook the roux until golden would darken the sauce, so this method keeps it pale and cooks out the raw flour taste without browning. Warm milk helps it blend smoothly, but cold milk also works when added gradually. Simmer gently until the sauce coats the back of a spoon, then season with salt, pepper and optional nutmeg. Warm milk in a small saucepan until steaming but not boiling. Keep nearby. Melt butter in a heavy saucepan over medium-low heat. Add flour and whisk 2 minutes without letting it brown. Pour in warm milk gradually, whisking constantly to keep the sauce smooth.
