Hey, I know I used a couple of terms in my last post that may leave some of you rubbing your head, but don’t be afraid of the four letter word roux or its much longer cousin…emulsions. You need to master a roux and an emulsion before you can be successful at composing fine “Mother Sauces.” So, let’s get to it.
A roux is a mixture of ingredients used to thicken sauces so they aren’t runny like water. The way to make a roux will leave you open-mouthed by its simplicity. You must use an equal amount of flour and fat (traditionally clarified butter and/or animal fats) mixed in a saucepan and cooked over medium heat. That sounds simple enough, but for how long do I cook it. Well, here’s the rub….how long you cook it depends on what type of roux you want. Unfortunately, no matter how long you cook it you won’t get a kangaroo! Couldn’t resist. Seriously, here’s how it works.
There are three generally accepted types of roux.
1. White Roux. Really, this should be named a yellowish roux, because that’s its true color, but who’s questioning history, eh? You will mix an equal amount of flour and clarified butter (if you are a purist) in a sauce pan and cook over medium head for just a few minutes until the fat and flour are well mixed and begin to get a little frothy. Don’t just pull the roux off the stove at this point, as you WANT to cook out the flour flavor. Also, you don’t want to leave it on so long that it turns a darker color, or you off and running into another type of roux. So, be careful how long you cook the White Roux. White Rouxs are used primarily for bechamel and alfredo sauces (in other words, sauces using bases such as milk and cream).
2. Blond Roux. Yep, Blond Roux. I can imagine a few of you “man cooks” out there hurrying to make a blond roux in hopes that she’ll be a dream come true. Well, she may be beautiful and slightly blond and she may make you happy, but she won’t last. Blond roux is cooked a bit longer than your White Roux. Cook it until it begins to turn a bit darker than the Yellow/White Roux. Blong Rouxs and used for stock based white sauces such as veloutes.
3. Brown Roux. You guessed it, a brown roux is a blond roux taken several steps further in the cooking process. The key to a perfect brown roux is to lower the heat and cook it over low heat (once it has combined and is frothy) until it browns evenly. Note, I said browns evenly, not burns or scorches. Interestingly enough, a brown roux cooked correctly will have a slightly nutty flavor and smell and taste quite rich. Yummmmm. You will use a brown route to thicken brown sauces like gravies.
Now for some tips for a great roux:
1. Never, never, never burn or scorch your roux.
2. A great roux is paste like and not runny or stew-like. Roux should not pour like liquid.
3. Cake flour makes by far the best roux.
4. Try not to use shortening as your fat. It add little flavor, tastes terrible and leaves a after greasing on your tongue.
5. Try to use clarified butter or another animal fat.
6. Make sure to use the correct amount of roux to complement the amount of liquids you have. I did some research of this one and here’s what the experts say. Personally, I just keep adding until I get the thickness I desire.
3 ounces of roux per quart of liquid will thicken into a thin consistency
4 ounces of roux per quart of liquid will thicken into a medium consistency
5 ounces of roux per quart of liquid will thicken into a thick sauce
6 ounces of roux per quart of liquid will thicken into a heavy gravy
So, how does one incorporate a roux? Well, again, it is really quite simple. A roux can be added to a liquid mixture when the mixture is warm to hot, but avoid early boiling, as clumps can form. Once the roux is added to the mixture you wish to thicken, make sure you whisk furiously until the liquid incorporates the roux (smooth and without any lumps). Next, bring the sauce to a simmer and continue to simmer and stir for 20 minutes or so. During this time the starchy flavor of the flour will further dissipate and your liquid will proceed to thicken. If you happen to have added to much animal fat, make sure you skim it off the surface.
Well, this had been good for me I hope it has been good for roux…………………….
