Heat and Browning
The three heat regimes, and the single transition each one risks
After this chapter, the next time a steak greys before it browns, a roast dries out before it crusts, a caramel jumps from amber to bitter, or a custard goes from set to scrambled — you'll know which of the three heat regimes was being asked to do the wrong job, and at which moment its transition was crossed.
The three heat regimes
Recipes call for “medium-high heat” without saying what that means in the cook’s pan, on the cook’s stove, with the cook’s volume. What is universal across stoves and pans is not a number on the dial; it is which of three regimes the heat is operating in. Name the regime, and the diagnosis follows.
- 01Convective regime — water-based — boiling, simmering, steaming, blanchingdoes well: extraction, hydration, gelatinisation
punishes: anything that needs surface browning - 02Contact regime — metal-based — searing, sautéing, pan-frying, stir-fryingdoes well: Maillard, fond, fast caramelisation
punishes: anything that needs slow even cooking through volume - 03Radiant regime — air-based — roasting, broiling, baking, broiler finishdoes well: even browning across surface, low-loss volume cooking
punishes: anything thin enough to scorch before its interior catches up
The chapter also covers the browning ladder (pale → golden → mahogany → dark → carbon), the Maillard / caramelisation vocabulary at home-cook depth, doneness windows for the main proteins with safety-aware notes, and eight worked examples from the catalog — from steak au poivre to yakiniku.
By the end of the chapter
- Heat as regime, not number. Why a single dial setting on the stove does different work in a steel skillet and a thin nonstick, and why the pan tells you more than the dial does.
- The three regimes on the same stove. Convective (water carrying the heat), contact (metal carrying the heat), radiant (air carrying the heat) — what each does well, what each punishes.
- The single transition each regime risks. Convective: water boils off and the regime quietly becomes contact. Contact: surface crosses from brown to scorch. Radiant: surface crosses from crust to char.
- The browning ladder. Pale, golden, mahogany, dark, carbon — and the half-step between mahogany and dark where most home cooks lose the dish.
- Maillard vs caramelisation, plainly. What each reaction needs, what colour each delivers, why they can both run in the same pan, and why neither one is the same as “burning.”
- Doneness windows with safety-aware language. Beef and lamb whole-cut windows, the cook-through requirement for ground meat / poultry / pork / fish, the carryover-cooking budget that finishes the protein after you pull it.
- Worked examples from the catalog. Eight recipes that walk the regimes in different cuisines.
- Reading your own pan. The visual and audible cues — the change in sizzle, the colour of the fond, the moment the steam stops rising — that announce a regime change before the thermometer does.
Eight recipes that walk the regimes
- Steak au poivre — contact regime, the decisive minute
- French onion soup — caramelisation as the entire dish
- Crème brûlée — radiant heat as the final theatre
- Bacalao al pil-pil — contact at the very edge of breaking
- Carbonara — convective into contact, off the heat before the egg sets
- Clam chowder — convective regime with mixed proteins
- Tarte Tatin — caramel carried unbroken through a bake
- Yakiniku — the contact regime distributed across a table
