German Potato Salad

This is less a recipe, than a suggestion. Because I don't measure often when I cook. Only when I bake.

But with
4 medium red potatoes
~ 3 tablespoons mayo
~2 tablespoons vinegar
~ 2 tablespoons whole seed mustard
4 slices of bacon, cooked and chopped. Using an ulu would have made this much easier, or if I had cooked it crispier.
