To oven-steam ribs, place ribs in a large baking pan, fill with about 1 inch of water, cover with aluminum foil and bake for about 50 minutes in a 350-degree oven. The recipe here includes instructions on how to boil ribs before grilling.
A rafter is one of a series of sloped structural members (beams) that extend from the ridge or hip to the wall plate, downslope perimeter or eave, and that are designed to support the roof deck and its associated loads. A pair of rafters is a couple.
In basic gable roof framing, rafters slope upward from the tops of the building's exterior walls and meet at the roof's peak, or ridge. The ridge board is a horizontal timber that serves as a nailing surface for the upper ends of the rafters but in most gable roofs does not bear any of the roof's weight.
