Ingredients:
16 whole habaneros
1 oz onion
1 clove garlic
2 tsp sugar
4 Tbsp white malt vinegar (or white wine vinegar)

Directions:
Blend all ingredients to whatever consistency you desire. I like to leave it still quite rough - like Bick's relish.
Heat to boiling and simmer for 20 minutes. Spoon the cooked sauce into a preheated preserve jar and seal.
Leave the jar in a cool, dark place for one month (at least) to develop a good flavour.
