With your pot still off the heat, add all the cheese. You can just dump it in all at once. Mix vigoursly (i bet your arm hurts with all the “vigorous mixing” we’ve done) for approximatly 10 minutes or until the cheese has completed melted into the roux mixture. (See the next video for how the texture should be).
* If the cheese seems to be a bit clumpy, but the burner on it’s very lowest setting and keep stirring!
