Crème brûlée (burnt cream) appears in English cookbooks as "burnt cream" at Trinity College, Cambridge, in the seventeenth century, and in French and Spanish cookbooks contemporaneously — its exact national origin is disputed and probably irrelevant. The preparation is so simple (cream, egg yolks, sugar, vanilla, baked in a bain-marie, sugar caramelised on the surface) that it was likely discovered independently in multiple places. What is certain is that the French adopted it, named it definitively, and made it the universal emblem of the Parisian bistro dessert from the 1980s onward after the Nouvelle Cuisine chefs — particularly Joël Robuchon and Michel Guérard — brought it back into fashion.
Crème brûlée is a cooked custard (crème anglaise consistency, set by heat in the oven rather than on the stovetop) with a surface of caramelised sugar applied by blowtorch. The custard should be set enough to hold its shape when the ramekin is tilted gently — not flowing, but barely. A correctly cooked crème brûlée trembles at the centre when the ramekin is nudged. This trembling (which the French call "le tremblotement") is the diagnostic of a correctly set but uncured custard. The bain-marie baking is essential — water surrounding the ramekins maintains an oven temperature of 100°C at the custard's surface regardless of the oven temperature above it, preventing the curdling that would occur if the custard were exposed to oven heat directly.
1. High-fat cream (36%+) produces a richer, more stable custard — lower-fat cream produces a lighter set that is more fragile during caramelisation 2. The sugar must be dry before applying — any moisture in the sugar (or on the custard surface) prevents even caramelisation and produces steam bubbles under the crust 3. The blowtorch distance and movement must be consistent — holding too close burns isolated spots; holding too far produces a pale, uneven crust. The torch moves like a painter's brush, never stationary. 4. Serve immediately after caramelisation — the crust begins absorbing moisture from the custard within 20 minutes, softening from glass to chew. Sensory tests: - **The tremblotement test:** Nudge the ramekin. The centre of the custard should tremble like very firm jelly — a brief oscillation that stops within 2 seconds. If it flows, it is under-set. If it is rigid with no trembling, it is over-set (curdled or over-cooked). - **The tap test:** Tap the caramelised surface sharply with the back of a spoon. A correctly set, cooled crust shatters cleanly — the sound should be a sharp crack, like breaking thin glass. A soft, padded sound means the crust is too thick, too warm, or the sugar was applied to a warm custard. - **Colour uniformity:** The brûlée surface should be even amber from edge to centre — no pale patches at the sides (where the torch didn't reach) and no dark brown spots at the centre (where the torch lingered). Uniform caramelisation is a skill developed over hundreds of repetitions.
