Honestly very confused by how it can be a mainstream condiment/dressing. For me it’s just acidic. Doesn’t really taste of much but sorta tingles on my tongue/throat. Sorta like when you burp up a little stomach acid or a milder version of when you throw up stomach acid. Very confused about salt and vinegar chips and any sort of vinegar based salad dressing.
For me vinegar’s contribution to foods is that it brings out hidden flavors from the other ingredients. But just a tiny amount is enough to do that. Any more and it’s kinda gross. I agree with everything op said.
