Made this for New Kids on the Block tag game. Since you just combined the sauce ingredients into a pan I first melted the butter, added the flour and cooked for a few minutes (making a roux), then wisked in the milk and added diced Velveeta and some onion and garlic powder and white pepper. I then proceeded with your recipe. I think next time I would cut the macaroni down a little or maybe just the cooking time. I enjoyed it but DH thought it was too dry for him.
