When it goes wrong · Barbecue
Bitter, acrid bark.
Can you save it?
Reviewed for this symptom
Trim the bitter surface away and serve the meat underneath, which is usually fine; fold the trimmed meat through a thin sauce if the bitterness runs deeper. Fix the fire before anything else goes on.
How to confirm the diagnosis
Observable cues, not inferred user state
- The bark tastes of creosote or an ashtray
- The smoke was thick and white or grey
- The fire was smouldering with the vents mostly closed
Not this?
What actually happened
Only this symptom
Too much smoke, or smouldering rather than clean combustion. A fire starved of air produces creosote; it needs to burn properly.
The full mechanism
Shared by every barbecue failure
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.
The full Barbecue lesson — how to tell, where to practise it, what it carries to.
Next time
Prevent this specific failure
Run a small, clean fire with the vents open until the smoke is thin and blue; never cook over thick white smoke.
What right looks like
Shared by every barbecue failure
- Thin blue smoke, barely visible. Thick white or grey smoke deposits creosote and makes the bark bitter.
- Doneness is probe feel — a skewer slides into the thickest part with no resistance, usually somewhere around 96-99°C.
- The bark is dark, dry to the touch and does not smear when pressed.
- The stall is a plateau, not a fault. The temperature genuinely stops climbing and it is not the thermometer failing.
