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 ↓
Baked Custard
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the custard
Whisk together the egg, sugar, and salt in a bowl.
Heat the milk until boiling, then gradually add it to the egg mixture, stirring constantly.
Bake
Pour the mixture into a baking dish and bake until firm in the center.
For caramel custard, melt 2‑⅓ cups of sugar until light brown, then add it to the boiling milk before mixing with the egg mixture.

Sugar and milk 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
- Egg
- Sets the custard into a firm, sliceable structure as it heats.
- Milk
- Forms the liquid base that the egg proteins set into custard.
- Sugar
- Adds sweetness and, when melted, can be cooked to brown for caramel flavor.
The step that matters
Heating the milk and adding it to the egg mixture gradually. Adding hot milk too quickly can scramble the egg proteins before the custard forms. Stirring constantly and adding it slowly lets the eggs warm evenly so the custard stays smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
