This is a modified version of a Betty Crocker recipe. It's ready after resting for 1 hour after preparation, but it should be made at least overnight, preferably 2 days in advance, to generate excellent sweetness and creaminess. The sour cream "kicks it up" just enough to generate a lot of compliments. I added a touch of vinegar, offset with sugar, which seems to greatly promote the development of flavor as it "ages". NOTE: I don't bother shredding the cabbage and carrot, I simply buy a 16 oz. bag of "shredded cabbage and carrots for cole slaw" in the salad veggies section of my supermarket. The listed prep time is based on that short cut.
