Cook half an onion in about a tablespoon of olive oil for about 20 seconds in the microwave (until onion is soft).

Add:
1½ cups of red wine
½ cup of chopped tomatoes
1 teaspoon tomato paste
1 tablespoon Emma's Apricot, Almond and Brandy Chutney

I also added 2 tsp Emma's Red Pepper & Chilli Sauce, a dash of Worcestershire Sauce and a dash of Soy Sauce

Heat the mixture for about 10 minutes on low power in the microwave. Stir regularly.

Add the leg to the mixture. Make sure that the leg is coated with the marinade.

Sprinkle some mustard seeds and mixed herbs on the leg.

After about 2 hours, turn the leg. Sprinkle some more mustard seeds and mixed herbs over the leg.

Allow to marinade for another hour.

Place meat on braai over moderate coals (here, a gas braai at 150°C).

Turn regularly, basting with marinade. Spoon onion, tomato and chutney mixture from the marinade over the leg.

After about 2 hours, the leg was ready to be carved.

Enjoy! (Here with an amber ale).
