To make your own vinegar you will need some unwanted alcohol.

Pour the bottle of wine into a large glass sterilised jar.

If you can get hold of some unpasteurised vinegar from a health food shop add about 200ml to the jar, this will speed the process up dramatically.

You can also add some ‘vinegar mother’ which is a jelly-like layer that forms on the top of unpasteurised vinegar; you can buy this online.

Cover the jar with muslin cloth and leave in a cool dark place and for two weeks.

After two weeks taste it – it should be tasting acidic by now and be ready in one more week. However, as it’s a living thing the flavour will keep developing.

The following recipe is for a herb-infused vinegar which you can adapt to your liking such as chillies, wild garlic, elderflowers for example. You can use your homemade vinegar or one that’s been bought.
