I served this sauce over broccoli and my kids loved it! The sauce does take a while to thicken--be sure to add the cornstarch & water mixture before the cheese and then let it GENTLY boil until it gets to the consistency you like before you add the cheese. It may also help to halve the recipe. Since it was just for the kids, I cut the recipe down to two servings (which was plenty), and had no problem with thickening. This is definitely a keeper!



This is just what I was looking for to put over brocolli. I had trouble with it not thickening enough so I added more cornstarch, probably another 1 or 2 T. mixed with the same amount of water. I used two 8oz. packages of shredded cheddar cheese instead. I seasoned with a dash of worchestershire and salt and pepper. This tasted great!



Seemed that there was way too much milk called for in this recipe. After 25 minutes of stirring with the cornstarch in, the sauce never thickened and after adding the cheese, still didn't get very thick at all.
