Macaroni and Cheese

Whenever I make macaroni and cheese the sauce goes grainy. I think it has something to do with cooking the cheese at too high of heat. Anyways, I made a nice creamy mac n' cheese and I'm so happy that I want to share with you the recipe. I use a macaroni and cheese recipe I found on epicurious.com and adapted it a little.

I didn't change the directions of the recipe, only the ratios of some of the ingredients which I've listed below:

Topping:
1 Tbsp. butter
1 cup bread crumbs
1/2 cup cheddar cheese

2 cups elbow macaroni

Sauce:
3 Tbsp. butter
3 Tbsp. flour
2 3/4 cup 2% milk
1/4 cup heavy cream
2 tsp. Dijon mustard
1/4 tsp. red pepper flakes
4 cup sharp (old) cheddar
salt and pepper for seasoning
