1. Make the Caramel Cream:
Caramelize the Sugar: In a medium saucepan, add 4 tablespoons of sugar. Heat over medium heat, stirring occasionally, until the sugar melts and turns a deep golden caramel color. This process requires patience—don’t rush it. The sugar will first clump up and then slowly melt. Be cautious as the caramel can quickly go from perfect to burnt.
Tip: Use a heat-resistant spatula and avoid stirring too vigorously to prevent crystallization.
Add Heavy Cream: Once the sugar is fully caramelized, carefully pour in 150 ml (⅔ cup) of heavy cream (for cooking). The mixture will bubble vigorously—be careful of splatters! Continue to whisk until the caramel and cream are fully combined and smooth.
Tip: If the caramel seizes up when adding the cream, gently heat and whisk until it returns to a smooth consistency.
Cool: Remove from heat and allow the caramel cream to cool completely. It will thicken slightly as it cools.
2. Make the Vanilla Cream:
Combine Ingredients: In a saucepan, whisk together 400 ml (1⅔ cup) of milk, 50g (⅓ cup) of vanilla custard powder (or cornstarch), and 4 tablespoons of sugar. Whisk until smooth.
Tip: Make sure there are no lumps in the mixture before heating to ensure a smooth custard.
Cook the Custard: Place the saucepan over medium heat. Continuously whisk the mixture until it thickens and begins to bubble. This should take a few minutes. Once thickened, remove from heat and let it cool completely.
Tip: Stir the custard occasionally as it cools to prevent a skin from forming.
Prepare the Cream: Once the custard is cool, whip 300 ml (1¼ cups) of heavy cream to stiff peaks. Gently fold the whipped cream into the cooled custard until well combined and smooth.
3. Make the Choux Pastry Dough:
Prepare the Dough: In a medium saucepan, combine 200 ml (¾ cup) of water, 50g (1¾ oz) of butter, and a pinch of salt. Bring to a boil over medium heat.
Tip: The butter should melt completely before adding the flour.
Add Flour: Once the mixture reaches a boil, reduce the heat to low and add 150g (1¼ cup) of all-purpose flour all at once. Stir vigorously with a wooden spoon until the dough forms a ball and pulls away from the sides of the pan.
Tip: Continue stirring for another 1-2 minutes to dry out the dough slightly. This step is crucial for achieving the proper texture.
Cool Slightly: Remove the pan from heat and let the dough cool for a few minutes until it is just warm to the touch.
Incorporate Eggs: Beat in the eggs one at a time, mixing well after each addition. The dough should become thick and glossy. It’s important to fully incorporate each egg before adding the next.
Tip: The dough is ready when it forms a smooth, shiny consistency and falls from the spoon in a thick ribbon.
