Unmarinated meat just doesn't have the flavor I care for, smoked, grilled or otherwise, and I can think of better things to do with my beer.
It depends on the meat, although I lean toward dry rubs for most of what I grill or barbecue. For a good steak, I rarely do anything more than sea salt, freshly-ground pepper and garlic powder. For chicken or pork I usually go for something a little more elaborate.
As one exception to my preference for dry rubs, though, I have a fantastic recipe for grilled pork loin that uses a paste of salt, pepper, rosemary, fresh garlic and olive oil. It’s one of my go-to dishes for when we have company, and it has been a big hit every time I have served it.
