I use the recipe on the side of the box of cornstarch. I usually change up the liquids to give it more of a creamy texture. So here is my recipe - usually I add a couple of tablespoons of cornstarch (blend it before adding it to the pan) to 3 cups of milk - salt and pepper to taste and a dash of dried mustard and a couple of tablespoons of butter or margarine. I slowly heat the milk until it thickens (add more cornstarch if necessary or more milk if its too thick) then I add grated cheddar cheese (2 cups) and remove the pan from the heat. Then I mix it all up with my cooked macaroni - put it in a casserole dish sprinkle bread crumbs - put in the oven at 350 until its lightly brown and crispy on top. Basically, I just increase the amount of liquids it calls for to give me the creaminess. I hope this helps. I forgot - I also add a couple of slices of American cheese to my cheese/milk mixture.
