After the cooking class, I was finally able to buy some rendered duck fat at Central Market. This is a cup of the fat and one and a half cups of flour after cooking for about twenty minutes. I would say that looks like it is peanut butter colored. Now, I need to wait until it has cooled down.
Mmmmmm, my house smells like heaven! I need to search for some pantone color samples of the different stages of roux.
