It is the best piece of barbecue trivia there is, and your pit master will explain it while it happens in front of you. The pink layer just under the crust of smoked meat is a smoke ring, and it is not undercooked meat. Burning wood produces nitric oxide, which dissolves into the damp surface of the meat and binds with myoglobin, the pigment in muscle, fixing it pink before the heat can turn it grey. It only forms early, while the surface is still cool and wet, which is why a good ring is a sign of real low-and-slow smoking rather than a shortcut.
Grilling does the opposite job. High, dry heat drives the Maillard reaction, named for the French chemist Louis-Camille Maillard, who described it in 1912, in which amino acids and sugars rearrange into hundreds of new aroma compounds. It is the entire reason a seared burger smells nothing like a boiled one.
The Southern Seafood menu leans on the first, with cedar-smoked salmon, hickory-smoked trout and a real lesson in wood-chip selection. The Grill and Chill and the Lamb and Wagyu menus lean on the second. Pick accordingly, or ask your planner which suits your crowd.
