Pastry cream is a French dessert essential—a cooked custard that is thickened with egg yolks and cornstarch, infused with vanilla, and enriched with butter for a glossy finish. It’s soft yet stable, making it ideal for piping into delicate pastries or spreading between layers of sponge cake. This “secret” version adds a touch of sophistication through a few clever enhancements: a splash of cream for silkiness, a dash of salt to round out the flavor, and a surprise infusion of citrus peel or coffee beans depending on the flavor direction. Once you master this, you’ll never go back to store-bought pudding or overly gelatinous fillings again.
Ingredients:
- 2 cups (500 ml) whole milk
- ½ cup (120 ml) heavy cream (secret twist for richness)
- 1 vanilla bean (split and scraped) or 2 tsp pure vanilla extract
- 6 large egg yolks
- ½ cup (100 g) granulated sugar
- ¼ cup (30 g) cornstarch
- 2 tablespoons (30 g) unsalted butter
- Pinch of salt
- Optional: citrus peel (lemon or orange for brightness) or crushed coffee beans (for a mocha version)
Instructions:
1. Infuse the Milk
In a medium saucepan, combine whole milk, heavy cream, split vanilla bean (or extract), and optional citrus peel or coffee beans. Heat over medium-low until small bubbles form around the edges—do not boil. Remove from heat, cover, and steep for 10 minutes to infuse. This step adds complexity and depth to the flavor. Strain if needed.
2. Whisk Yolks and Sugar
In a heatproof mixing bowl, whisk together the egg yolks, sugar, and salt until pale and slightly thickened—this should take about 1–2 minutes. Whisking well now helps prevent clumps later.
3. Add Cornstarch
Sift the cornstarch over the yolk mixture and whisk until fully blended. You’re aiming for a smooth, lump-free paste. It may look thick—that’s perfect.
4. Temper the Eggs
Slowly drizzle about ½ cup of the warm milk mixture into the yolk bowl while whisking constantly. This step gradually raises the temperature of the yolks, preventing them from scrambling when added back to the pot.
5. Cook the Custard
Pour the tempered egg mixture back into the saucepan with the rest of the milk. Cook over medium heat, whisking constantly and vigorously—make sure to get the corners of the pan. In about 2–4 minutes, the mixture will thicken. Don’t walk away! Once big slow bubbles appear (like thick lava), cook for 1 more minute to eliminate any starchy flavor.
6. Finish with Butter and Chill
Remove from heat and stir in the butter until melted and glossy. Transfer the pastry cream to a wide, shallow dish (to speed cooling), press plastic wrap directly on the surface to prevent a skin, and refrigerate until completely cool—at least 2 hours.
Tips for Success:
- For Extra Shine & Smoothness: Add a teaspoon of unsalted butter when reheating the pastry cream to revive its luster if prepping ahead.
- Flavor Variations: Mix in rose water, espresso powder, or a spoonful of fruit purée after cooling for customized fillings.
- Texture Fix: If lumps form, don’t worry—just blend briefly with an immersion blender or push through a fine sieve.
