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.
5

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.

Recipe FAQ

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.
