Grandma's Homemade Mac & Cheese

I've posted this recipe before, but have never been able to capture a picture!  Here it is and here is the recipe once again!

Grandma's Homemade Mac & Cheese
yields 9 x 13 inch casserole dish

Ingredients:
2 tbl butter
2 tbl flour
1/2 tsp salt
1/2 tsp ground mustard (dry mustard)
1/4 tsp pepper
a couple pinches of sugar
2 - 3 cups milk (I lean torward 2 1/2 to 3)
1 cup cubed velveeta cheese
2 1/2 - 3 cups elbow macaroni

Method:
Melt butter in saucepan.  Mix in flour & seasonings with a wisk.  Continue to heat over medium heat for a few minutes.  Mix in milk with wisk (this may take a few minutes for flour/butter mixture to disolve).  Bring milk to a boil while continuously stirring so it doesn't stick to the bottom of your saucepan.  Once boiling turn heat down and stir in cheese until melted and combined.  If you have time, store cheese sauce in fridge for a couple hours to thicken up.
Boil macaroni until tender, then drain.  Pour macaroni into 13 x 9 in casserole dish.  Reheat cheese sauce, then pour over macaroni to coat it.  Slice extra velveeta thinly w/ a cheese slicer and layer over the top of mac & cheese.  Broil in oven watching very closely until browned as desired.
