so this was great for us. I did not use one cup of salt as suggested because some reviews on another site said they had to toss the entire batch of potatoes out. I used a couple of teaspoons salt in boiling water, non-fat sour cream, and a good mayonnaise. A taste test of the dressing suggested it need some acid, so I added 1 tablespoon of pineapple vinegar, then added another 1/2 tablespoon. So, be sure and do a taste test for your likes. I also small diced the red onion. It got better each day.
Some non-fat sour cream has sugar, we like a brand called Enjoyably Yours Fat-Free Sour Cream, which does not list sugar in the ingredients list.
Oh, I did not do all the fuss with the potato water. Simply cook the potatoes, let cool, made dressing, and combined.
