My BBQ sauce:
3-4 cloves of garlic, chopped and put in a pan with some canola oil on a low heat. After 5-10 minutes I add a cup of brown sugar, and let it caramelize for a moment. Then I add a few tablespoons of white wine vinegar (or apple wine vinegar), and about half a cup of the cheapest scotch I can find (For some reason I try to avoid Merkan whiskey, even though it would probably be more authentic in BBQ sauce). Then I add cup of ketchup, and then come the seasonings. First a lot of salt, but this you will have to decide according to your own taste. Then some oregano, cayenne pepper, some chili powder, and a heck of a lot of both paprika, and Cajun seasoning. Sometimes I add some dried coriander too. Oh, and black pepper. Then I just cook it for maybe 15 minutes, and turn off the heat and let it cool. It's delicious with both chicken and pork.
