What follows are the requirements for the perfect barbecue restaurant. To start, the locale must be family-owned — preferably by kin who've been running the joint for 20 years or more. Smoke from burning hickory must waft through the air. If possible, its blazing aroma should reach beyond the parking lot and into the street. There must be peerless pulled pork, beef ribs, pork ribs, and brisket. Side orders should include collard greens, beans, and cornbread. The only permissible salad is coleslaw. All other greenery must be paired with fried chicken. It is preferable if paper towel rolls and squeeze bottles, holding house-made sauces, are the only furnishings atop the picnic tables. Last, and perhaps most important, the restaurant must be located in an off-center, peripheral spot that, ideally, requires a lengthy drive. The best barbecue is always worth driving for, and no place merits the travel more than Shiver's BBQ in Homestead — an old-school shrine to smoke and hogs that fulfills all of those requirements and so much more.
