The real version, you blanch the skins off of gold potatoes. No sugar added.
my grandparents on my dads side came here after ww2. I made the mistake once of leaving the skins on the potatoes, and let’s just say my grandmother, who didn’t really like me anyway(or any kid to be honest), made damn sure I never forgot it. Her parents owned a generational restaurant in Sttugart prior to it getting leveled in the carpet bombings of the town. She was very particular about any thing German dish wise. Her job as a teenager growing up was to make the potatoe salad. And no, she never did give out that recipe. Took it to her grave.
