Black garlic barbecue sauce recipe
 A sticky, smoky black garlic sauce makes a great accompaniment for meat, vegetarian recipes and fish. Black garlic, of East Asian origin, is mellower and sweeter than its raw cousin. Aged in controlled environments over several weeks, it adds extra depth to recipes and perfectly enhances this barbecue garlic sauce. 100ml/3½fl oz olive oil4 red onions, roughly chopped2 cooking apples, cored, peeled and chopped2 red chillies, chopped2 black garlic bulbs, cloves separated and peeled2 rosemary springs150g/5½oz soft dark brown sugar1 tbsp sweet or hot smoked paprika 1 tbsp English mustard powder1 tsp salt 2 tbsp black treacle 150ml/5fl oz balsamic vinegar100ml/3½fl oz dark soy sauce 500ml/18fl oz apple juice 1.5 litres/2½ pints tomato passata 100ml/3½fl oz olive oil 4 red onions, roughly chopped 2 cooking apples, cored, peeled and chopped 2 red chillies, chopped 2 black garlic bulbs, cloves separated and peeled 2 rosemary springs 150g/5½oz soft dark brown sugar 1 tbsp sweet or hot smoked paprika 1 tbsp English mustard powder 1 tsp salt 2 tbsp black treacle 150ml/5fl oz balsamic vinegar 100ml/3½fl oz dark soy sauce 500ml/18fl oz apple juice 1.5 litres/2½ pints tomato passata Method Heat the oil in a large flameproof casserole over medium-high heat.
