Why it works: Chocolate and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chocolate Custard
Ingredients
Directions
Make the custard
In a saucepan, combine the grated chocolate and fresh milk over medium heat.
In a separate bowl, beat the egg yolks until light, then gradually add the sugar while continuing to beat.
Once the chocolate and milk mixture comes to a boil, remove it from heat and slowly pour it into the egg yolk mixture, stirring constantly until smooth.
Return the mixture to the saucepan and stir briskly for 5 minutes until thickened.
Add the egg whites
Beat the egg whites until stiff peaks form and fold them into the custard when it begins to harden in the freezer.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Gives the custard its chocolate flavour and a rich, smooth body.
- Fresh milk
- Forms the liquid base that the custard thickens into.
- Egg yolks
- Thicken the custard as they heat and add richness.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
- Egg whites
- Whipped to stiff peaks, they lighten the custard with an airy texture.
The step that matters
Adding the hot milk to the yolks. Pouring the hot chocolate milk into the yolks too fast can scramble them. Adding it slowly while stirring constantly warms the yolks gently, so the custard thickens smooth rather than lumpy.
