Of all the desserts that sound intimidating and taste impressive, crème brûlée might offer the best return on effort. There is no pastry to laminate, no whipped egg whites to fold, no delicate flip to execute. It is, at its core, a custard baked gently in the oven and finished with a caramelised sugar top — two simple stages, each easy to understand once you know what you are actually doing at each one.
Stage One: Making the Custard
A crème brûlée custard is built from just four ingredients — egg yolks, cream, sugar, and vanilla — but the ratio and the method matter more than the ingredient list suggests.
Why yolks only. Egg yolks contain fat and emulsifiers that set into a smooth, rich custard, while egg whites (used in dishes like flan) firm up more rigidly. Using yolks alone is what gives crème brûlée its signature silky, spoonable texture rather than a wobbly, sliceable one.
Warming, not boiling, the cream. Heat the cream gently with the vanilla until it is steaming, not bubbling. This step infuses flavour and slightly thins the cream, making it easier to combine with the yolks in the next stage.
Tempering the eggs. This is the step most home cooks skip and regret. Whisk the yolks and sugar together, then add the warm cream very slowly, a little at a time, whisking constantly. Adding it too fast scrambles the yolks instantly; adding it gradually raises their temperature evenly, keeping the mixture smooth.
Straining. Always pass the custard through a fine sieve before baking. This removes any stray bits of cooked egg or vanilla pod, guaranteeing the glassy smoothness that defines a good brûlée.
The water bath. Custards should never bake directly in a hot, dry oven — the direct heat cooks the edges too quickly while the centre lags behind. Instead, ramekins sit in a tray of hot water, which insulates them, allowing gentle, even cooking. The custard is ready when the edges are set but the centre still has a gentle wobble, rather like set jelly.
Stage Two: The Brûlée
Once chilled, a thin, even layer of sugar goes on top — just enough to cover the surface without pooling into a thick layer. A kitchen blowtorch is the ideal tool here: it melts and caramelises the sugar in seconds, without warming the cold custard underneath. Move the flame constantly in small circles, watching the sugar shift from clear, to amber, to a deep golden brown. Stop just before it darkens further, since sugar can go from perfectly caramelised to bitter within moments. No torch at home is not a dealbreaker — a very hot grill (broiler) works too, though it warms the custard slightly more, so serve promptly.
How It Compares to Its Cousins
Crème brûlée belongs to a wider family of baked custards, and understanding the differences helps clarify why each behaves the way it does.
Flan uses whole eggs rather than yolks alone, giving it a firmer, sliceable set that can be unmoulded onto a plate. Instead of a bruléed top, it is baked with a layer of liquid caramel poured underneath, which becomes a sauce once inverted.
Crema Catalana, the Spanish-Catalan cousin, is thickened on the stovetop with cornflour rather than baked in the oven, and is flavoured with citrus zest and cinnamon rather than vanilla. Its caramelised sugar top is bruléed just like crème brûlée’s, but the custard beneath is made through an entirely different process.
Pot de crème is closest in spirit to crème brûlée — same rich, yolk-based custard, same water bath — but it is served without any caramelised top at all, letting the custard itself be the whole point.
Each dessert takes the same basic idea, an egg-thickened dairy base, and pulls it in a different textural direction.
Classic Crème Brûlée
Serves 4
Ingredients
- 500ml double cream
- 1 vanilla pod, split, or 2 tsp vanilla extract
- 5 large egg yolks
- 75g caster sugar, plus extra for the topping
Method
- Preheat the oven to 150°C (130°C fan).
- Heat the cream and vanilla in a saucepan until steaming, then remove from heat and let infuse for 10 minutes.
- Whisk the egg yolks and sugar together until pale. Slowly pour in the warm cream, whisking constantly.
- Strain the mixture through a fine sieve into a jug.
- Divide between four ramekins set in a deep roasting tray. Fill the tray with hot water halfway up the ramekins.
- Bake for 35–40 minutes, until set at the edges with a slight wobble in the centre.
- Chill for at least 4 hours, or overnight.
- Sprinkle a thin, even layer of sugar over each custard and caramelise with a blowtorch until deep golden. Let sit for 1–2 minutes before serving.
