Roux[ROO] A mixture of flour and fat that, after being slowly cooked over low heat, is used to thicken mixtures such as soups and sauces. There are three classic roux white, blond and brown. The color and flavor is determined by the length of time the mixture is cooked. Both white roux and blond roux are made with butter. The former is cooked just until it begins to turn beige and the latter until pale golden. Both are used to thicken cream and white sauces and light soups. The fuller-flavored brown roux can be made with butter, drippings or pork or beef fat. It's cooked to a deep golden brown and used for rich, dark soups and sauces. CAJUN and CREOLE dishes use a lard-based roux, which is cooked (sometimes for almost an hour) until a beautiful mahogany brown. This dark nutty-flavored base is indispensable for specialties like GUMBO.Also note: I don't cook anything with a roux simply because I have enough time to slow-cook everything. I like the complete natural flavor of what I'm preparing rather than the artificial taste of the roux. AND .. If you burn, however slightly, a roux, the taste is absolutely horrible and will ruin your dish!!
NOTE: The use of a ROUX is still a very HOT and controversial topic in some circles.
Hey, we could tell ya how everybody else makes a ROUX, like all those "Fancy-Shmancy" Chefs and so-called authors of all those On-Line Cookbooks and such that probably don't know one end of a spatula from the other ... Here's how my Grandmother made a ROUX:
Add BUTTER (however much you want) in a "Black-Iron" Skillet over LOW HEAT !!
NOTE: Butter has a very low burn temperature. Add a little olive oil or other high-temperture oil/lard/fat if necessary.
Stir in enough FLOUR (plain) to thicken (careful not to allow LUMPING) and cook constantly stirring (Important!!) on LOW HEAT until the desired color is attained.
That's all there is to it .....
