This came from a friend of mine who lived in TN who passed away about 5 years ago. Her Grandmother always made this and it is an excellant dressing. It is a tad sweet so you can cut back on the sugar if you like but I find it even better after it has sat over night so the potatoes have a chance to soak up the flavors! I also add cut up hard boiled eggs to my potato salad. To be honest I have no idea how much it makes and how many servings. I make this when I am having company and I boil about 5 lbs of potatoes and it cover that amount.
