Smoke Ring

The pink ring just under the bark of smoked meat, formed by nitric oxide from burning wood reacting with myoglobin.

The famous pink ring around brisket and ribs is NOT proof the meat is undercooked or that it's saturated with smoke flavor. It's a chemical reaction: nitric oxide (NO) and carbon monoxide (CO) from combustion bond with myoglobin in the meat's surface, locking in pink color even after cooking. The ring usually stops developing around 140°F internal. Cooking on a pellet grill produces a smaller ring than charcoal — but the meat tastes the same.

Why it matters

Don't sweat the size of your smoke ring. It's pretty, but it's not flavor.
