In most of south Louisiana that answer is -Yes.
But Can You ?
- Begin making the roux by melting 1 cup of clarified butter in a saucepan over medium heat. Once the butter is hot enough that a pinch of flour sprinkled into it will slowly start to bubble, proceed to the next step.
- Whisk 1-3/4 cups of flour into the clarified butter until a thick, rough paste forms. Whisk constantly while it bubbles over medium heat. As it cooks, the roux will become smooth and begin to thin.
- The white stage is reached once the flour looses its raw smell, after about 5 minutes of cooking and stirring. Although slightly grainy in texture, it is much smoother than it was at the beginning. The mixture is bubbling vigorously and the color is a little paler than when the clarified butter and flour were first combined.
- After about 20 minutes of continuous cooking and stirring, the roux will reach the blond stage. The bubbles are beginning to slow, and the aroma has taken on nuances of popcorn or toasted bread. The roux is now tan colored, very smooth, and thinner than it was at the white stage.
- Brown roux will reach a peanut butter-brown color after approximately 35 minutes of cooking and stirring. Its aroma is more pronounced and sharper than the nutty nuances of blond roux. The roux is now thinner, and the bubbling has slowed even more.
- Even darker than brown roux, the dark brown stage occurs after about 45 minutes of cooking, and is the color of melted milk chocolate. Its aroma will also mellow from the strong, roasted flavor of brown roux and will actually smell a little like chocolate. The roux is no longer bubbling, and is very thin.
- Carefully pour the finished roux onto a baking sheet and place in the refrigerator to cool.
- Refrigerate the roux for several hours or overnight until it has hardened completely. Once hardened, it is easily pried off of the baking sheet and broken into pieces. If you used oil or a fat other than clarified butter, the flour may settle to the bottom, and the oil will rise to the surface. Stir the oil back into the flour before using as this will make the roux dissolve smoothly. If you decide to pour off the oil, the roux will still work, but will require more whisking into a sauce in order to fully dissolve.
Roux will keep indefinitely when stored in the refrigerator or freezer in an airtight container. Roux made with vegetable oil can be stored at room temperature for several weeks, but roux made with butter or fat should always be refrigerated. With perfectly prepared roux always on hand, making luxuriously silky soups and sauces will be a breeze!
