I had a craving for that bbq char flavor last weekend so I decided to grill up some chicken thighs and legs except I realized that I didn't have a bottle of BBQ sauce. No biggie, coz I have ketchup, vinegar and brown sugar. Those 3 ingredients are the base of a bbq sauce and you could pretty much add whatever else you want to create a flavorful bbq sauce that you'd be so proud ...
