I prefer onion vinegar! But my point merlin is once you've fully loaded your fish n chips with salt and drowned it in vinegar, then you'd be left with vinegary green goop, and as a kid the vinegar used to drip and pour out of the chip wrapper onto my trainers and trousers, with mushpeas leaking onto my clothes would'nt it look like ive got some kind of dodgy radiation sickness? lol!
