Ingredients
- ½ cup (100 grams) granulated sugar – Provides sweetness and helps with the custard’s consistency.
- ¼ cup (32 grams) cornstarch (or cornflour) – Thickens the custard and gives it a smooth texture.
- 2 cups (480 ml) whole milk – Creates a rich and creamy base.
- 4 large egg yolks – Contribute to the custard’s thickness and silkiness.
- 3 tablespoons (45 grams) unsalted butter, sliced into tablespoon-sized pieces – Adds richness and a velvety finish.
- 2 teaspoons pure vanilla extract – Enhances the flavor with warm, aromatic notes.
Instructions
1. Mix the Dry Ingredients
In a large saucepan, whisk together the granulated sugar and cornstarch. Combining these two before adding liquid ensures the cornstarch doesn’t clump when heated. Set the saucepan aside.
2. Prepare the Egg Mixture
In a separate mixing bowl, whisk the egg yolks and milk together until fully combined. This step helps distribute the egg yolks evenly, preventing any lumps in the final custard.
3. Combine Wet and Dry Ingredients
Slowly pour the egg-milk mixture into the saucepan with the sugar and cornstarch while whisking continuously. This helps incorporate everything smoothly.
4. Cook the Mixture
Place the saucepan over medium heat and stir constantly with a whisk or rubber spatula. As the mixture heats, it will gradually thicken. Once it starts to boil, continue stirring and allow it to cook for one more minute. The custard should now be thick enough to coat the back of a spoon.
5. Add Butter and Vanilla
Remove the saucepan from heat. Stir in the butter, adding one piece at a time until fully melted. Then, mix in the vanilla extract.
6. Strain and Chill
To ensure an ultra-smooth consistency, strain the custard through a fine-mesh sieve into a heat-proof bowl. This removes any tiny lumps that may have formed. Cover the surface with plastic wrap, pressing it directly onto the custard to prevent a skin from forming. Refrigerate for at least 2 hours.
7. Whisk Before Using
Once chilled, give the pastry cream a quick whisk before using it to smooth out any firmness that developed in the refrigerator.
Notes
How to Avoid Common Mistakes
- Preventing Curdling: If the custard starts to curdle (scrambled eggs appearance), it means the heat was too high or it wasn’t stirred consistently. Cooking over medium heat and stirring constantly will prevent this.
- Fixing Lumps: If your pastry cream has lumps, don’t panic—simply pass it through a fine-mesh sieve while it’s still warm.
- Checking for Doneness: Pastry cream is ready when it thickly coats the back of a spoon. If it’s too thin, continue cooking for another 30 seconds to a minute.
- Avoiding a Skin Formation: Always press plastic wrap directly onto the surface of the custard before chilling to prevent an unappetizing skin from forming.
Efficient Kitchen Tips
- Prepare Ingredients in Advance: Measure everything before you start cooking to ensure a smooth workflow.
- Use a Rubber Spatula: This tool is ideal for stirring since it scrapes the bottom and sides of the saucepan, preventing scorching.
- Chill Quickly: If you need to cool the pastry cream quickly, place the bowl in an ice bath and stir until it reaches room temperature before refrigerating.
