Rescues · TO BARBECUE
No smoke ring.
Why it happens
Cosmetic and irrelevant to flavour. It forms early, only in the presence of combustion gases, and its absence says nothing about the cook.
Recovering it
Undercooked is fixed by more time, always. A stall that has gone on for hours is ended by wrapping in foil or butcher paper. Dry meat cannot be rehydrated, but shredding it and folding through the rendered juices or a thin sauce recovers most of the eating quality — which is exactly what pulled pork is. Bitter bark cannot be fixed and should be trimmed away.
The mechanism
Barbecue is not grilling with a lid — it is a braise in dry air with smoke added. The temperature is held low, roughly 105-135°C, and the food is never over the fire. Two slow processes run in parallel. Collagen hydrolyses into gelatin, which needs hours held above about 70°C and is what turns a brisket or a shoulder from inedible to tender. Meanwhile smoke deposits phenols and carbonyls on the surface, building the bark, and nitrogen dioxide from combustion reacts with myoglobin to form the pink smoke ring — which is a chemical marker, not a doneness signal. The stall is the phenomenon that surprises everyone: somewhere around 70-75°C the internal temperature stops rising for hours, because evaporation from the surface cools the meat as fast as the fire heats it. Wrapping stops the evaporation and ends the stall.
