Crème brûlée appears to be one of the simplest desserts in the French repertoire — a few ingredients, a specific technique. Yet it fails for predictable reasons in home kitchens: the custard is overcooked (produces a texture with bubbles and an eggy flavor), the sugar crust is uneven (burnt in spots, not melted in others), or the custard hasn't been cooked in a water bath and the edges set before the center.
The three techniques that matter: the water bath, the barely-set test, and the sugar caramelization.
Why the Water Bath (Bain-Marie)
The custard in crème brûlée is delicate. Egg proteins (primarily ovalbumin) set at around 80°C and become tough and rubbery at higher temperatures. The custard is baked in an oven set to 160°C, but the water bath surrounding the ramekins keeps the temperature around the custard from exceeding 100°C (the boiling point of water), which would otherwise cause the egg proteins to over-coagulate at the edges while the center remains raw.
How to set it up: Place ramekins in a deep baking pan; pour hot (not boiling) water into the pan until it comes halfway up the sides of the ramekins.
The Custard Ratio
- 5 egg yolks per 500ml heavy cream (double cream)
- 50–60g sugar (to taste)
- 1 vanilla bean (or 1 teaspoon pure vanilla extract)
- No whole eggs — whole eggs produce a firmer custard; crème brûlée should be silky and barely set
The Barely-Set Test
Crème brûlée is done when:
- The edges are fully set and don't move
- The center has a slight wobble when the pan is shaken — like a just-set Jell-O
- A small area in the very center (1–2cm diameter) wobbles visibly
If the entire surface wobbles, it needs more time. If there is no wobble at all, it may be slightly overcooked (still very good, but loses the ideal silky center).
The custard will continue to set as it cools — it should come out of the oven looking slightly under-done.
The Sugar Crust
1–2 teaspoons of fine sugar (caster sugar or superfine sugar) are spread evenly over the cold custard surface. The sugar is caramelized with a kitchen torch (preferred) or under a broiler:
Torch method: Move the torch in a circular motion from 8–10cm above the surface; the sugar will liquify, then begin to caramelize (amber color). Stop when fully caramelized but not dark-brown or burnt.
Broiler method: Place ramekins on a tray under a very hot broiler, 3–5cm from the heat source. Watch constantly — the difference between perfectly caramelized and burnt is 20–30 seconds. The broiler heats less evenly than a torch.
Allow to harden for 1–2 minutes before serving. The caramel sets hard at room temperature. It should be cracked with the back of a spoon in a single decisive strike — the crust cracks through; the spoon reaches the soft custard below.
The Complete Recipe
Makes: 4 ramekins | Time: 1.5 hours + 4 hours chilling
Ingredients
- 500ml heavy cream (double cream, 36%+ fat)
- 5 egg yolks
- 50g caster (superfine) sugar
- 1 vanilla bean, split and scraped (or 1 teaspoon vanilla extract)
- Additional sugar for the crust: 2 teaspoons caster sugar per ramekin
Method
1. Infuse the cream: Combine cream and vanilla bean (pod and scraped seeds) in a saucepan; heat until just barely simmering — small bubbles around the edges. Do not boil. Remove from heat; steep 15 minutes. Remove vanilla pod.
2. Make the custard: Whisk egg yolks and sugar together until slightly pale and combined. Gradually pour the warm cream into the yolk mixture, whisking constantly (tempering — adding hot liquid gradually to prevent the eggs from scrambling). Add vanilla extract if not using vanilla bean.
3. Strain: Strain through a fine mesh sieve; press gently. This removes any cooked egg bits and the vanilla bean fibers.
4. Skim foam: A foam will form on the surface of the custard. Skim it or pop bubbles with a spoon — foam on the surface creates pits in the finished custard.
5. Pour into ramekins: Divide among 4 standard ramekins (120–150ml capacity).
6. Water bath: Place ramekins in a deep baking pan; pour hot water until halfway up the sides of the ramekins. Cover the entire pan loosely with foil.
7. Bake: 160°C (325°F), 30–35 minutes until the edges are set and the center still wobbles.
8. Cool: Remove ramekins from the water bath; cool to room temperature; refrigerate minimum 4 hours (overnight is better).
9. Caramelize: Spread 2 teaspoons sugar over each cold custard; caramelize with a torch or broiler. Serve immediately after the crust has hardened.
