must admit that I do love malt vinegar and putting it on fries/chips adds flavor that I enjoy... add adding apple cider vinegar at the table when having boiled dinner - ham or corned beef- makes the cabbage easier to digest... we also use a good mustard or mustard sauce with wild abandon lol

vinegar is a prime ingredient in both mustard and ketchup/catsup... so not sure where the objection to straight vinegar comes from... but to each their own

and while I do salt my food, I've cut back on how much I use because I want the enhance not overwhelm the food's flavor... and processed food is mix of salt, sweet and grease far too often
