Steph's Macaroni and Cheese (Grumpy's holiday request)

Ingredients:
1/2 stick butter
2 cups elbow macaroni
1/2 cup flour
1 1/2 cups milk, plus some
1 cup (roughly 1/3 of a big block, I guess) Velveeta, cut into small cubes
2 cups shredded cheddar (mild or sharp, depending on preference/availability)
Garlic powder
Cavender's Greek Seasoning
Black pepper

Preparation:
1. Cook macaroni. Overcook it by about 3 minutes. It should be just slightly "mushy" on the outside, but not very much. Drain and put in a large mixing bowl.

2. Melt butter in small saucepan over medium heat.

3. Shake together flour and 1 cup of the milk. Pour into melted butter, stirring constantly.

4. Cook butter/milk/flour mixture until the consistency of gravy, adding milk as necessary to keep it from getting too think. Stir constantly as it thickens so that it doesn't get lumpy.

5. Add Velveeta cubes to mixture, stirring until all cubes are melted. If mixture is thicker than gravy, add some milk to thin it.

6. Add garlic powder, Cavender's and pepper to taste. Overseason slightly, since, the macaroni will be mixed with the sauce.

7. Pour cheese sauce over macaroni, and stir to coat. Add 1 cup of the shredded cheddar and mix.

8. Put mixture into 9x13 casserole dish (or similar). Top with remaining shredded cheddar.

9. Bake at 350 degrees until cheese on top is melted and casserole is a little bubbly.
