Best uses for malt vinegar...

Sprinkle lavishly over your fish, chips and mushy peas.

Or mix with sugar and chopped mint, for the classic British sauce to go with lamb (although traditionally, at this time of yearwe’re still on mutton (or hogget) and onion sauce for a while yet - and, indeed, that is tonight’s dinner)

Other than that, I really only use it when making pickles and chutneys.
