Instructions: Step-by-Step Guide to Making Perfect Pastry Cream
1. Heat the Milk and Vanilla
In a medium saucepan, pour in the milk and add the vanilla extract or scraped vanilla bean (if using). Heat the milk over medium heat until it’s hot but not boiling. You want to scald the milk, meaning it should be steaming with small bubbles around the edges but not actively boiling. Stir occasionally to prevent the milk from scorching.
2. Whisk the Egg Yolks, Sugar, and Cornstarch
While the milk is heating, place the egg yolks, granulated sugar, cornstarch, and salt in a medium-sized bowl. Whisk them together until the mixture is smooth, pale, and thickened slightly. This is the base for your custard.
3. Temper the Egg Mixture
Once the milk is hot, you need to slowly add it to the egg mixture without cooking the eggs. This process is called “tempering” and is crucial to avoid scrambling the eggs. Start by adding a small amount of the hot milk into the egg yolk mixture while whisking constantly to bring the temperature of the eggs up. Gradually add the rest of the milk in a slow stream, whisking constantly as you pour.
4. Cook the Pastry Cream
Return the combined egg and milk mixture to the saucepan and place it over medium heat. Continue to whisk constantly as the mixture begins to thicken. It will start to bubble around the edges and then thicken into a custard-like consistency. Keep whisking to ensure it doesn’t stick to the bottom of the pan.
Once the pastry cream has thickened and is starting to boil (it should coat the back of a spoon), continue cooking for 1-2 more minutes to ensure the cornstarch is fully cooked and the cream is smooth.
5. Finish the Pastry Cream
Remove the saucepan from the heat. If using a vanilla bean, remove the bean pod from the mixture. Whisk in the butter, if using, for added richness and smoothness. Stir until fully melted and incorporated. The butter will give the cream an extra silky texture.
6. Cool the Pastry Cream
Pour the pastry cream into a clean bowl or shallow pan. Cover it with a piece of plastic wrap, pressing the wrap directly onto the surface of the cream to prevent a skin from forming. Let it cool to room temperature before refrigerating.
Refrigerate the pastry cream for at least 2 hours before using. It will thicken as it cools and become the perfect consistency for filling pastries.
Tips for Perfect Pastry Cream
- Don’t Rush the Tempering Process: Adding the hot milk too quickly can cause the eggs to scramble. Patience is key here. Add the milk slowly, whisking constantly, to ensure the eggs are evenly tempered and the custard stays smooth.
- Whisk Constantly: Once the custard begins to cook on the stove, whisk constantly to prevent it from curdling or sticking to the bottom of the pan. This also helps incorporate air, keeping the cream light and silky.
- Adjust Sweetness and Flavor: While vanilla is traditional, pastry cream can be flavored in a variety of ways. You can infuse the milk with lemon zest, orange peel, or even a cinnamon stick. You can also make chocolate pastry cream by melting some chocolate into the custard after cooking, or add a splash of your favorite liqueur for an adult twist.
- Use Fresh Eggs: Since pastry cream relies heavily on eggs, using fresh, high-quality eggs will give your cream a richer color and flavor.
How to Use Pastry Cream
Once your pastry cream is ready, there are countless ways to use it. Here are a few ideas:
- Fill Tarts and Pies: Spoon pastry cream into pre-baked tart shells or pie crusts, then top with fresh fruit or a drizzle of caramel sauce.
- Eclairs and Cream Puffs: Pipe the pastry cream into light and airy eclairs or cream puffs for a classic French treat.
- Layer Cakes: Use pastry cream between layers of sponge cake or genoise to add moisture and richness to your cakes.
- As a Filling for Danish Pastries or Croissants: Spread pastry cream inside flaky croissants or Danish pastries for a delightful breakfast or dessert treat.
- As a Standalone Dessert: For a simple dessert, serve chilled pastry cream in small bowls, topped with berries or a dusting of cocoa powder.
How to Store Pastry Cream
Pastry cream should be stored in an airtight container in the refrigerator for up to 2-3 days. If you’re not using it immediately, be sure to cover the surface of the cream with plastic wrap to prevent a skin from forming. If you find that it thickens too much after refrigeration, simply whisk in a little bit of milk to loosen it up before using.
