Store-bought sauces are easy and there are a lot of good choices out there, but when you make your own BBQ sauce, you get to control the quality of the ingredients, and you can adjust the flavor to your liking. If you like sweet flavors, add more brown sugar or honey. If you like a more tangy flavor, add more vinegar. Also, it takes less than an hour to make your own sauce, so you can prepare it while your meat is smoking.
