How to Make It
Place firewood and/or natural lump charcoal in base of grill, and ignite. Once fire has burned down and coals are glowing orange and white and have reached medium-high (400˚F to 450˚F), place 3 to 4 dozen oysters, cupped side down, on grill grate. Grill, covered, until oysters just begin to open at the wide end, 8 to 10 minutes. Discard any that do not open.
Use tongs to carefully transfer hot oysters to a serving platter, retaining as much liquid as possible. Let stand until cool enough to handle with a towel, 10 minutes. Using an oyster or paring knife, pry open oysters, discard top shells, and place on the half shell on the platter. Serve immediately. Repeat with remaining oysters.
