Cookbook:Roux

Cookbook | Ingredients | Recipes | Sauces

Roux is a basic cooked mixture of varying ratios of flour and fat (usually butter), useful for making sauces, and for thickening soups or gravies. The benefits of using a roux include: It does not have to be cooked very long to remove a floury taste, clumps of flour are removed, and it creates unique flavors. It can be cooked to different degrees (from white to brown) depending upon the intended use, and a darker roux (one that has been cooked longer) will also be thicker and have more flavor, but will have less thickening power.

Variation I

Ingredients

A basic roux may be composed of equal parts flour and butter by weight.

Procedure

1. Melt the butter in a thick-bottomed sauce pan over medium heat, then add flour.
2. Mix well and cook to desired color, stirring constantly to prevent burning. This may well take up to twenty minutes.

Notes, tips, and variations

• Depending upon how you plan to use your roux, you may need to add the sauce's other ingredients before the roux is fully cooked.
• One way to use a roux, is to add liquid to it, stirring it in as you go. Don't go the other way, adding the roux to the liquid, as you will get lumps. Once enough liquid has been added to the roux (you'll know), you can safely add it back into another liquid.
• A good roux will have a slight shine to it, and neither the texture nor the taste of the flour will be apparent.
• When making a dark roux, switching from butter to an oil with a high smoke point (such as soybean oil or Canola oil) will allow for a higher cooking temperature, decreasing cooking time. Keep in mind that different fats will give the roux a somewhat different taste.

Variation II

Ingredients

• 8 fl oz clarified butter
• 8 oz flour

Procedure

1. Mix the flour and butter in a very thick saucepan, and put it on the side of the fire or in a moderate oven.
2. Stir the mixture repeatedly so that the heat may be evenly distributed throughout.
3. For a white roux, cook for a few minutes, just to do away with the disagreeable taste of flour. For a blond roux, cooking must cease as soon as the colour of the roux begins to change, and before the appearance of any colouring whatsoever. Brown roux is ready when it has acquired a fine, light brown colour and when it exudes an odour resembling that of the hazel-nut, characteristic of baked flour.

Notes, tips, and variatioins

• It is very important that brown roux should not be cooked too rapidly. When cooking takes place with a very high heat in the beginning, the starch gets burned within its shrivelled cells. The binding principle is thus destroyed, and double or triple the quantity of roux becomes necessary in order to obtain the required consistency. But this excess of roux in the sauce chokes it up without binding it, and prevents it from clearing. At the same time, the cellulose and the burnt starch lend a bitterness to the sauce of which no subsequent treatment can rid it.
