Salt and vinegar is a classic chip flavour in Britain and North America. Liquid vinegar would make chips soggy, so makers use vinegar powder, usually vinegar dried onto maltodextrin, or acids such as sodium diacetate, which carry the sharp, sour taste in dry form.
The example on SeekSnack is Herr’s Salt & Vinegar Potato Chips from Herr’s, a Pennsylvania snack maker. Among the big potato chip flavours, salt and vinegar stands out as one built on sourness rather than on cheese, spice or sweetness.
Salt and vinegar seasonings are usually free of milk, unlike cheese or sour cream flavours, though some brands use malt vinegar, which comes from barley and contains gluten.
