Instructions

1

Split the vanilla bean lengthwise and scrape out the seeds. Add seeds and the pod to the milk in a saucepan. Bring to a simmer, then turn off heat and steep for 5 minutes.

Tip: Steeping infuses the milk with deep vanilla flavor.
2

In a bowl, whisk egg yolks, sugar, and cornstarch until pale.

Tip: Cornstarch protects the egg proteins from curdling too quickly.
3

Remove the vanilla pod. Slowly pour the warm milk into the egg mixture while whisking constantly.

Tip: This is called 'tempering'—gradually introducing heat to the eggs to prevent them from cooking instantly.
4

Pour the mixture back into the saucepan. Cook over low heat, stirring constantly, until thickened to a custard-like consistency. Do not boil vigorously!

Tip: The sauce is ready when it coats the back of a spoon (nappe consistency).
5

Stir in the lemon zest and fresh blueberries. Cook for 2 more minutes, just until berries warm through and soften slightly.

Tip: Lemon zest adds brightness to cut the richness of the custard.

Recipe FAQ

Why did my sauce scramble?
You likely poured hot milk into the eggs too quickly or boiled the mixture after combining. Tempering and gentle heat are key!
Can I use vanilla extract?
Yes, but real vanilla bean specks offer a superior flavor and visual appeal.
