Roux (/ËruË/) is flour and fat cooked together and used to thicken sauces.[1] Roux is typically made from equal parts of flour and fat by weight.[2] The flour is added to hot oil on the stove top, blended until smooth, and cooked to the desired level of brownness.
Roux is made by stirring the flour into the melted butter and then cooking it for a few minutes so that the floury taste cooks off. Then, the roux can be used or cooked further to develop more color and a toasty flavor. Roux can also be made with other fats such as lard, bacon fat or simple vegetable oil.oux (pronounced roo) is a mixture of equal parts (by weight) fat and flour that is used for thickening sauces and soups.
