Since I don't have my Grandmother's mac & cheese posted (blush), I went looking for one similar & this is it!! I doubled the sauce as my box of elbows was 16oz. and I like LOTS of cheese sauce. I personally prefer extra sharp cheddar. Grammy also puts a layer of American cheese in the middle (put 1/2 macaroni & cheese in baking dish, layer 4-5 slices cheese, add the rest of the mac & cheese). Like you, she puts grated cheese on top instead of breadcrumbs! Happy Easter!
