- Why did the sauce scramble?
- You poured milk that was too hot onto the eggs, or boiled the sauce with the eggs in it. 'Tempering' is key!
- Can I use vanilla essence?
- Yes, but the black seeds of a real vanilla pod elevate the dish aesthetically and in flavour.
Blueberry vanilla custard sauce
This recipe is a simplified, cornflour-stabilised version of the classic Crème Anglaise with a fruity twist. The warm, comforting scent of vanilla and the freshness of blueberries create a dessert sauce that elevates the simplest sponge cake to a masterpiece. The egg yolks provide richness, while the cornflour prevents curdling.

Instructions
1
✓
Split the vanilla pod lengthwise and scrape out the seeds. Place the pod and seeds into the milk in a saucepan. Bring to a boil, then turn off the heat and let it steep for 5 minutes.
Tip: During steeping, the vanilla flavour 'migrates' into the milk (infusion).
2
✓
In a bowl, whisk the egg yolks with the sugar and cornflour until pale.
Tip: Cornflour protects the egg proteins from sudden coagulation.
3
✓
Remove the vanilla pod from the milk. Slowly pour the warm (but not boiling!) milk into the egg mixture in a thin stream while whisking constantly.
Tip: This is 'tempering': gradually accustoming the eggs to the heat.
4
✓
Pour everything back into the saucepan. Cook over low heat, stirring constantly, until it thickens (custard consistency). Do not boil vigorously!
Tip: The sauce is ready when it coats the back of a spoon.

✓
Stir in the lemon zest and fresh blueberries. Cook for another 2 minutes, just until the blueberries warm through and soften slightly but don't fall apart.
Tip: Lemon zest adds freshness to the creamy custard.
