Here's what I use for my slaw. I often start with the shredded cabbage slaw mix from the store (I'm the only one who eats slaw, wife/GoFaresBoy turn their noses up at it, amongst many other good foods). For the dressing, I mix about 1/4 cup of Hendrickson's dressing (made in the STL area) with about the same amount of mayo. The Hendrickson's has a good blend of sweet and sour. The mayo makes it white.

That's it.
My mom in CAK turned me onto the Hendrickson's, and I used to only get it up in that area. Now, Krogers down here in WV carry it, and so did WM at one point, but not now.
For sauce, I've been using Bone Suckin' Sauce from down RDU way. Their hotter variety is not too hot, but has a nice kick.
