Why it works: Egg and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set and add richness to the texture.
- Milk
- Forms the liquid base that the eggs thicken into a custard.
- Sugar
- Adds sweetness and balances the flavor of the eggs and milk.
The step that matters
Cook in a double boiler without stirring. Gentle indirect heat lets the egg proteins set slowly and evenly. Direct high heat or stirring can scramble the eggs or make the custard grainy.
