Basting the meat while cooking helps keep it moist and is a great way to add additional flavors. The baste should be applied with either a basting mop or a spray bottle. If you use a spray bottle, the ingredients must be mostly liquids with soluble powders. Don't use a basting brush as it will brush off the dry rub seasonings. Basting sauces should contain 50% oil and 50% acid (vinegar, citrus, etc.). To that mixture, you may add additional ingredients such as onion and garlic powder, ground pepper, etc. If you are going to make a generous amount of baste (or mop sauce), then you may use celery, onion, garlic, carrots, etc. and then strain the ingredients before using.
Apply baste every 30 minutes 1/2 the way through cooking (i.e. baste the last have of the overall cooking time).
