This is the recipe Greg from The Penguin & Pinky's (local burger joints) came up with & it kicks serious ass. It's so far removed from the nauseating crap in the tubs I had as a kid that I almost want to call it something else. It's a great melter, good on burgers, on cheese fries and, of course, on white bread for a sandwich. I anticipate making some soon to add to Mainley's peirogies. The mayo content is lower, which helps it out as a melting cheese but it does require you to mix a lot more. For the mayo, Duke's is the best choice here. It's tangier than the other brands & that really helps. If you live someplace where Duke's is not available I suppose you could add a few drops of vinegar or lemon juice. I haven't tried that but it could work.
