The science and craft of cooking with live fire and smoke. Covers heat management, wood selection, smoke penetration, stall management, and the difference between low-and-slow and hot-and-fast approaches. Also encompasses high-heat pan cooking, which shares the same Maillard-driven logic as grilling.

Key questions

  • How does wood species affect smoke flavour at different temperatures?
  • What causes the stall in brisket and how do you manage it?
  • When does wrapping help vs. hurt bark formation?
  • How do kamado, offset, and pellet smokers differ in outcome?

Barbecuing: McGee's Definition

Barbecuing is low-temperature, slow heating of meat in a closed chamber by hot air from smouldering wood coals — around 200°F/90°C. It is a dry-heat method that produces smoky, fall-apart tender meat over several hours.

The best arrangement: wood burned in a separate chamber; the meat in a second connected chamber so there is no direct radiation from the coals — only the relatively cool smoke (~200°F) transfers heat, doing so inefficiently and therefore gently. Large cuts (slabs of ribs, pork shoulder, beef brisket) take several hours to reach 165–170°F/75°C internal temperature.

The "smoke ring" — the permanent pink or red zone under the crust of barbecued meats — results from the slow, gentle heating that allows more myoglobin to remain intact during the long cook.

The Searing Myth (Liebig)

Searing does NOT seal in juices. The German chemist Justus von Liebig proposed this around 1850. It was disproved within decades and remains disproved. The crust around seared meat is not waterproof — the continuing sizzle in the pan is the sound of moisture escaping. Moisture loss is proportional to meat temperature; high-heat searing dries the surface more than moderate heat.

However: searing generates intense Maillard flavours on the surface that make meat delicious. Sear for flavour, not for juice retention. The two are compatible — just know why you're doing it.

Two-Stage Cooking

The most reliable method for meats that need both a browned surface and a properly done interior:

  1. High heat briefly — sear both sides for a few minutes to generate Maillard crust
  2. Low heat to finish — transfer to oven or reduce burner heat, cook through gently

The benefit: at low temperatures, the gradient between surface and centre is small. More of the meat is within a few degrees of the target temperature, and the window of time in which the interior is at the correct doneness is much larger. This makes it far harder to overshoot.

Grilling: Infrared Radiation

Grilling and broiling work primarily via infrared radiation — direct energy emission from the heat source. Glowing coals and electrical elements reach ~2,000°F/1,100°C; gas flames reach ~3,000°F/1,650°C. This is vastly hotter than oven walls (~500°F max), which is why grilling browns food so quickly.

Best practice: hot zone for surface browning (2–3 min per side), then move to cooler zone to cook through. Starting meat at room temperature (rather than cold from the fridge) shortens the time the outer layers spend exposed to high heat.

Pan Searing

Cast iron or heavy steel pan searing is the indoor equivalent of direct-heat grilling:

  • Get the pan properly hot — oil just smoking before the meat goes in
  • Don't move it — leave undisturbed for 3–4 minutes; moving disrupts Maillard
  • Batch cook to avoid steaming — crowding drops pan temperature; cold wet meat causes steaming, not searing
  • Press flat cuts down — firm contact with the pan ensures even browning
  • Watch glazed meats — high-sugar glazes (mirin, maple syrup) caramelise fast; reduce heat if it starts to blacken

Butterflying

Opening a thick cut by slicing horizontally (like a book) and bashing to even thickness (~2cm) ensures uniform cooking. Critical for lean cuts like pork loin.

Resting

Non-optional. As meat temperature drops, its water-holding capacity increases — it reabsorbs some lost juice. For pan-seared thin cuts: minimum 5 minutes. For large roasts: 30+ minutes (some chefs equal to the roasting time). Carve at ~120°F/50°C internal, not piping hot.

Wood and Smoke

The chemistry of wood smoke is covered in detail in wood-smoke. Key operational principles for live-fire cooking:

  • Target thin blue smoke, not billowing white. Thin blue = clean pyrolysis; white = water vapour and acrid early-combustion compounds still present.
  • Wood species selection is a lignin question. Mesquite (~64% lignin) is intense and can overwhelm on long cooks. Oak (~28%), hickory (~18%), and fruitwoods (apple, cherry, ~18–20%) are more forgiving and balanced. High-lignin woods produce more guaiacol — the core "smoky" flavour compound.
  • Manage fat drip to control PAHs. Polycyclic aromatic hydrocarbons (carcinogens) form primarily when fat drips onto coals or open flame and undergoes incomplete combustion. A drip pan beneath the meat is the most practical prevention.
  • The smoke ring forms when nitrogen dioxide from wood smoke reacts with myoglobin — the same chemistry as nitrate-cured meats. It stops deepening at ~170°F/75°C surface temperature and is a visual indicator of smoke exposure, not a doneness marker.
