Mom's Macaroni and Cheese

I finally decided to try a new recipe in our Betty Crocker Cooking Basics cookbook. Usually, if we have macaroni and cheese, we have Trader Joe's gluten-free boxed version. It's cheap and easy to make. However, our grocery store had some gluten-free elbow macaroni on sale last week and we stocked up, so I figured making our own macaroni and cheese with the elbow macaroni would be a good idea.
