1. Infuse the Milk
- Heat the Milk: In a medium saucepan, heat the milk over medium heat until it begins to steam but doesn’t boil. If using a vanilla bean, split it lengthwise, scrape out the seeds, and add both seeds and pod to the milk. Remove from heat and let it steep for 10 minutes to infuse the flavor.
- Strain (if needed): If you used a vanilla bean, strain the milk through a fine sieve to remove the pod and seeds. Return the milk to the saucepan.
2. Prepare the Egg Mixture
- Whisk the Yolks: In a medium bowl, whisk the egg yolks and sugar together until pale and creamy, about 2-3 minutes.
- Add Dry Ingredients: Sift the cornstarch and flour into the egg mixture. Whisk until smooth and thick. This step ensures the cream will thicken properly without lumps.
3. Temper the Egg
- Gradual Heating: Slowly pour half of the warm milk into the egg mixture, whisking constantly to prevent the yolks from cooking. This is called “tempering.”
- Combine Mixtures: Pour the tempered egg mixture back into the saucepan with the remaining milk.
4. Cook the Pastry Cream
- Thicken the Cream: Place the saucepan over medium heat. Whisk constantly as the mixture heats. It will start to thicken noticeably after a few minutes.
- Boil for Perfection: Once it thickens, bring it to a gentle boil and cook for 1-2 minutes to eliminate any raw starch flavor. Whisk continuously to prevent scorching.
5. Finish with Butter
- Add Butter and Vanilla: Remove the saucepan from heat and immediately whisk in the butter until smooth. If using vanilla extract instead of a bean, add it now for the freshest flavor.
6. Cool the Pastry Cream
- Transfer and Cover: Pour the pastry cream into a clean bowl. Press a piece of plastic wrap directly onto the surface to prevent a skin from forming.
- Chill: Refrigerate for at least 2 hours, or until completely cold. Once chilled, whisk it briefly to restore its silky texture before using.
Pro Tips for Succes
- Use Whole Milk: The fat content in whole milk ensures a creamy, luxurious texture.
- Prevent Lumps: Whisk constantly during cooking and don’t rush the thickening process.
- Flavor Variations: Add citrus zest, almond extract, or a splash of liqueur (like Grand Marnier) to customize your pastry cream.
- Stabilize for Warm Climates: Add 1 teaspoon of powdered gelatin dissolved in a little water for a firmer cream that holds up in heat.
Where to Use Pastry Cream
- Filling Desserts: Use it in éclairs, cream puffs, fruit tarts, or Boston cream pie.
- Layering Cakes: Spread between cake layers for a decadent touch.
- Topping Desserts: Pipe onto doughnuts or serve as a base for trifles.
Storage Tips
- Refrigeration: Store in an airtight container for up to 3 days. Always whisk before use.
- Freezing: Pastry cream doesn’t freeze well due to its delicate texture. Use it fresh for the best results.
