Lazy Gravy

I used this at Thanksgiving and I'll never make gravy another way.

A few TBS of pan drippings (or more if you have them)
4 TBS butter
4 TBS flour
2 to 4 cups of stock (Use if you don't have drippings)
1/3 cup cream
salt and pepper to taste

Remove grease from drippings using a separator. In a small bowl, cut together the butter and the flour. With your fingers mash them together into a smooth paste. Over medium heat, heat the drippings, add the butter-flour mixture, stirring until it melts, then whisk in a bit of stock. Cook, stirring for a few minutes. Gradually add more liquid and cook until thick. When all the liquid has been added and it is thickening - add the cream and salt and pepper to taste.
