Most of the time, we think of thickening soups and sauces with a roux, which is a mix of flour and fat added at toward the start of cooking. But a slurry added toward the end of cooking is another easy way to get a thicker, more luxurious sauce without a lot of fuss!

Think of a slurry as almost the opposite of a roux. A roux is cooked, uses fat, and is added at the beginning of cooking. In comparison, a slurry is uncooked, needs no fat, and is added at the end of cooking.
