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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks set as they heat, giving the custard its body and firm texture.
- Milk
- Provides the liquid base and moisture that keeps the custard smooth and creamy.
- Chocolate
- Supplies the chocolate flavour and some richness to the custard.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
The step that matters
Slowly pour the boiling milk over the yolks. Egg proteins set at high heat, so adding the hot milk gradually while stirring constantly warms the yolks evenly. Pouring too fast can scramble them and leave the custard lumpy.
