Yesterday in Kroger (a supermarket for you non-Americans) I saw a bunch of cans of potato salad. Why would someone buy canned potato salad?
Even if you don't want to make it, I've never been in a supermarket that doesn't offer a fresher option. I've even been in gas stations that offer what they at least claim is fresh potato salad.
Maybe if you really, really wanted potato salad and you were in a food desert but the corner 7-11 has canned potato salad you might buy it, but I've never seen this before in my life.
Mayo vs vinegar is kind of an actual debate in germany. The civilised side and the vinegar people are mostly blissfully unaware of each other until they develop righteous hatred for the other salad as soon as they learn of it. I heard the vinegar version is eaten warm, which sounds even worse. I would say both are authentic, but vinegar potato salad is authentically horrible.
Storebought potato salad will also at best get people talking behind your back in germany, no matter which kind.
I've lived in both regions and both versions are strictly inferior to a potatoe salad based on mustard (+ oil and broth). The vinegar version uses a bit of mustard, but I'm speaking of mustard being the main ingredient. Naturally, I'm hated by both sides.
This sounds so much like Spanish potato omelette. There's the civilised side and the side that add onions to the omelette.
And you don't want to bring the topic to any peaceful conversation.
Because you use broth, fresh beef broth (or a hearty vegetable one) and vinegar just as a spice. The South is looking very critical at the rest of Germany with their weird abominations they call potato salad
