Ingredients:
12 red chillies (as hot or as mild as you like)
600ml white wine or cider vinegar
1/2 tsp black peppercorns
Method:
Trim the ends from the chillies and split open (remove the seeds and membranes for a milder effect). Add the vinegar to a pan, bring to a boil then add the chillies and peppercorns. Return to a boil then take off the heat and allow to cool slightly. Pour into a sealable jar (a Kilner jar is ideal) then cover and set aside to stand in a sunny position of at least four weeks.
After this time, strain the mixture through a fine-meshed sieve lined with muslin. Discard the solids then seal the resultant vinegar in sterilized bottles.
