Homemade Vanilla Custard Sauce
AI-written · not yet kitchen-tested
With custard sauce, temperature is everything: at about 170 to 175 °F (77 to 80 °C) the yolks thicken the sauce, and from about 185 °F (85 °C) they curdle into scrambled-egg flakes. So you stir without pause over low heat and take the pot off the heat in time. A kitchen thermometer makes it foolproof.

Ingredients
- 500 ml (2 cup) whole milk
- 1 vanilla bean split lengthwise, seeds scraped out
- 4 egg yolks from large eggs, as fresh as possible
- 60 g (2.1 oz) granulated sugar
- 1 tsp cornstarch makes the sauce less prone to curdling
- 1 pinch salt
Method
- Heat the milk with the vanilla seeds and the scraped pod in a saucepan over medium heat until it steams and bubbles rise at the edge. Do not let it boil. Take the pot off the heat, cover it and let the vanilla steep for 10 minutes.
- Meanwhile whisk the egg yolks, sugar, cornstarch and salt in a mixing bowl for about 2 minutes, until pale and creamy.
- Remove the vanilla pod from the milk. Pour the hot milk in a thin stream into the yolk mixture while whisking constantly, not the other way around, so the yolks do not set.
- Pour the mixture back into the pot and heat over low heat, stirring constantly with a wooden spoon and sweeping the whole bottom of the pot. After 5 to 8 minutes the sauce turns slightly thick and reaches 170 to 175 °F (77 to 80 °C).
- To test it, dip the spoon in and draw a line with your finger across the back of the spoon. If the track stays clear and the sauce does not run together, it is done. Take it off the heat immediately; it must not boil.
- Pour the sauce at once through a fine sieve into a cold bowl so it stops cooking. Stir, press plastic wrap directly onto the surface and serve it lukewarm or cold. In the refrigerator it keeps for 2 days at most.
Tip: If the sauce has curdled slightly anyway, take it off the heat at once, pour it into a cold bowl and beat it vigorously with an immersion blender or a whisk. A tablespoon of cold milk helps.
Tip: Here the eggs are heated to 170 to 175 °F (77 to 80 °C). For small children, pregnant women, older people and anyone with a serious health condition, make the sauce fresh, keep it cold and use it within 2 days.
