Why it works: Milk and egg 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 ↓
Brown Custard
Ingredients
Directions
Make the custard
In a tin dish, add 2 tablespoons of sugar and let it dissolve slowly until it caramelizes.
Pour in 1 pint of boiling milk very slowly to avoid foaming.
Combine the caramelized milk with 2 egg yolks, 1 egg white, and 2 tablespoons of sugar, mixing well.
Return the mixture to the stove and heat until it just begins to boil.
Top and serve
Beat the 2 egg whites to stiff peaks and place on top just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Caramelizes to give the custard its brown color and sweet, toasted flavor.
- Egg yolks
- Thicken the milk mixture into a rich custard as they set with gentle heat.
- Egg whites
- Beaten to stiff peaks, they form a light, airy topping for the custard.
- Milk
- Forms the liquid base of the custard and dilutes the caramel into a smooth sauce.
The step that matters
Heat the custard only until it just begins to boil. Egg yolks thicken as they warm, but overheating can curdle them into grainy lumps. Stopping at the first sign of boiling keeps the custard smooth.
