How do you make bbq sause?

BBQ Sauce ingredients: 2 tablespoons veg oil, 1 onion (finely chopped), 3 garlic cloves (minced), 1 and a half cups ketchup, half a cup cider vinegar, a quarter cup Worcestershire sauce, a third of a cup sugar, 1 tablespoom chilli powder, half a tablespoon cayenne pepper (or as needed) How to make: warm the veg oil on medium heat in a saucepan. Add onion and garlic and cook gently, stirring for 5 min. Add rest of ingredients (the more cayenne you add, the hotter it will be.) Reduce heat and simmer, partially covered, until the sauce thickens slightly, for about 20 min. Should make 2 and a half cups. Tips: make sure onions are finely chopped, or the sauce will be lumpy. Great for BBQ Ribs.
