noun. milk thickened with a butter and flour roux.
1. Noun, singular or mass Unlike beurre manie, the flour and butter in bechamel are cooked to a golden color before you add the milk, so you make this Alfredo extender in a separate sauce and whisk it into the finished Alfredo. 2. Adjective You could go all green by choosing spinach noodles and stirring some of the spinach filling into a white, bechamel sauce, or you could use white noodles so the spinach filling and while cheeses stand out.
