BBQ sauce is a simple recipe which you can alter and experiment with as you go along. It is mostly used either as a dip or a marinade.
2 tbsp sunflower oil
1 large onion finely chopped
1 tbsp tomato puree or 2 tbsp ketchup
2 tbsp brown sugar
1 large tsp mustard powder
2 tbsp Worcestershire sauce
150 ml water
Heat the oil and cook the onions until they are translucent. You can add a clove of garlic for extra flavour.
Add all the other ingredients and bring to a rolling boil, except the tomato, which should be added last and beaten into the mixture. Cook for about 10 minutes.
This recipe has no salt, but you can add 1/2 teaspoon to keep it for about 2 weeks in the fridge. You can whizz the sauce to produce a smooth dip. However, it is great added to pork on a BBQ just as it is!
