This is an easy recipe that my great-Aunt Damiana (Nellie)used to make for me when I was a little kid. I found out that her mother used to make it for her family when SHE was a kid! So, this recipe is over 100 years old! The secret to this recipe is mixing the butter and cheese into the macaroni while it is still hot, thus some-what melting the cheese on contact with the macaroni. Also, it is the Fontinella cheese that gives this recipe it's unique taste.
