I like a tangy potato salad, and of German ancestry so I don’t always use mayo. We (like my Omi always did) sprinkle the vinegar over the newly sliced, warm potato slices in the wooden bowl. Somehow potato salad in a wooden bowl just is right. Then you can cool the potatoes and put the rest of the seasonings on them (and mayo) when cooled. But the vinegar on the warm potatoes seals in the tang.
Sounds good, Yaelle. I think jonrick would be interested in your recipe too.
