Tips on How to Get Creamy Macaroni and Cheese

I am on a mission to make sure no one has grainy homemade mac n cheese ever again… and in my research discovered this awesome tip. Do NOT put the pan back over the heat to melt the cheese. The ingredients in the pan are already hot enough to do the job of melting the cheeses.

If you get cheese too hot that is when you will end up with a grainy texture. After you have stirred in the cheese, pour the mixture over the cooked noodles, and watch the melting commence!
