Ingredients and Measurements
- 2 cups Heavy Cream (36% Fat)
- 5 Large Egg Yolks
- 1/2 cup Granulated Sugar
- 1 Vanilla Bean
- Extra Sugar (for caramelization)
- Hot Water (for Bain-Marie)
Preparation Instructions
- Infusion: Split the vanilla bean and scrape the seeds into the cream. Heat the cream until it just reaches a simmer. Remove from heat and steep for 15 minutes to extract the vanillin and essential oils.
- The Custard Base: Whisk egg yolks and sugar until pale. Gradually temper the warm cream into the yolks to prevent scrambled eggs (thermal shock).
- Filtration: Pass the mixture through a Chinois (fine-mesh sieve) to remove the vanilla pod and any chalazae. This ensures a perfectly silken texture.
- The Bain-Marie: Pour the custard into shallow ramekins. Place in a baking pan and fill with hot water until it reaches halfway up the sides. The water acts as a thermal buffer, limiting the temperature to 212°F.
- The Bake: Bake at 300°F (150°C) for 35-45 minutes until the edges are set but the center still ‘jiggles’ like gelatin. Internal temp should reach 170°F-175°F.
- The Chill: Refrigerate for at least 4 hours. The cold temperature stabilizes the lipid-protein matrix.
- The Torching: Sprinkle a thin, even layer of sugar on top. Use a blowtorch to caramelize the sugar until it forms a hard, glass-like amber shell.
History: The Burnt Cream of the 17th Century
From the Trinity College to the French Court.
The first written recipe for ‘Crème Brûlée’ appeared in François Massialot’s 1691 cookbook, Cuisinier roial et bourgeois. While the French name is now definitive, the dish has English roots as ‘Burnt Cream,’ famously served at Trinity College, Cambridge. The technique of topping a soft custard with a brittle layer of burnt sugar was a 17th-century innovation. It remained a dormant classic until the 1980s, when New York’s Le Cirque restaurant popularized it, sparking a global revival that turned the simple custard into a symbol of fine-dining elegance.
Technical Focus: Lipophilic Stability and the Glass Transition of Sugar
Managing the Structural Set.
Crème Brûlée is a study in lipid management. The high fat content of the heavy cream (36%) coats the egg yolk proteins, preventing them from bonding too tightly. This results in a creamy, rather than rubbery, set. The ‘crack’ of the top layer is achieved through the glass transition of sugar. As the torch heats the sucrose, it melts and then rapidly cools, forming an amorphous, non-crystalline solid (glass). This brittle shell provides a critical textural contrast to the soft, lipophilic custard beneath.
Ingredient Dossier: Egg Yolks
The Emulsifying Engine.
Egg yolks are a complex mixture of water, lipids, and proteins, specifically vitellin. They contain lecithin, a powerful natural emulsifier. In custard production, the yolks serve as the structural backbone; as they are heated, the proteins uncoil and form a three-dimensional network that traps the liquid cream. From a technical perspective, the ratio of yolks to cream determines the ‘richness’ and the setting point of the dessert, with the high fat content of the yolks contributing to the velvety mouthfeel.
