Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Chocolate Custards
Ingredients
Directions
Make the custard
Dissolve the chocolate gently by the fire in the water until smooth.
Boil the mixture, then add the milk flavored with lemon peel or vanilla.
Stir in the sugar and bring to a boil.
Gradually stir the hot mixture into the beaten eggs, straining it as you go.
Cook and serve
Pour the custard into a jar or jug and place it in a pan of boiling water.
Stir continuously until the custard thickens.
Let it cool before transferring to glasses or a dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the chocolate flavor and dark color of the custard.
- Eggs
- Thicken the custard as they set with gentle heat, giving it body and richness.
- Milk
- Forms the liquid base of the custard, adding creaminess and softness.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
The step that matters
Stir continuously until the custard thickens. Egg proteins set gradually with gentle heat. If the custard gets too hot or is left unstirred, the eggs can curdle or scramble, leaving a grainy texture.
Swap the lemon
