Beth you may have just answered a long time mystery for me...This is the first time I have really read the foods board and though this thread has been here a while I wanted to reply to it....I remember from my youthful days the get togethers and the old KY hill women bringing or making their baked Mac-n-Cheese, and it had a certain perfect Sweetness touch to it I have never been able to achieve. And your recipe may be the clue I was looking for with using the canned milks...even non sweetened evaporated canned milks seem to have a touch of sweetness to them that regular milk does not.

Where I came from in the hills, milk was not always a household staple, not the bottled/carton/jug whole milk type anyway, as the local store did not offer refrigerated foods, you had to go "up Town" for that, but powedered and canned milks were always in the cupboards of just about all households and were regularly used in cooking. So Remembering that and seeing your recipe I may just be on to something here.......I plan on trying this in the near future and will let you know how it turns out.
