Here's the Carnation Evaporated Milk brand's recipe for Fudge. It also has a variation to make different flavors of fudge too, a little lower on the page after the recipe. Haven't tried it yet tho. I'm sure it's a winner since it's a recipe I've even seen posted on a premade Carnation Fudge kit at Giant Eagle grocery store. Lord knows the recipe I tried not too long ago was a flop.
