Jodi's Mac and Cheese

I just got this recipe from my friend, Jodi, and tried it tonight for supper..let me tell you, I have made zillions of recipes for mac and cheese and didn't like any of them as much as Kraft Mac and Cheese from the box, but this one is GOOD.  It's so simple that I was wondering about it, but glad I took the leap of faith and went for it. 

All she does is cook enough macaroni to feed you family..I cooked a few cups of elbow macaroni..about halfway or so..mine said cook 11 minutes and I cooked it about 6-7 minutes.  drain.  in a buttered casserole dish start making layers with the macaroni, shredded real Kraft American cheese (I used slices because I had them) -do not use velvetta- and dots of butter.  I made three layers ending with the cheese and butter on the top.  pour a can of evaporated milk-must be evaporated milk-over the mixture.  LIGHTLY salt and pepper the top.  the cheese has salt in it remember.  Bake at 325 for one hour.  YUM.
