My mom's potato salad is unique, to say the least. She boils the potatoes (and a few eggs), peels & dices the potatoes, peels and slices the eggs. The sauce is maynonaisse (no Miracle Whip!), sour cream, dehydrated onion and sweet pickle relish, and the mystery ingredient - ketchup! I think we're the only ones to have "pink" potato salad!! LOL The egg slices are used as a garnish on top, then sprinkled with paprika.
I'm not really sure where she came up with the recipe. I like it and I like most others as long as there is no mustard involved. I'm really fond of German-style potato salad, but it's hard to find (has a vinegar based dressing).
