Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Caramel Custard
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Scald the milk in a saucepan but do not boil it.
In a bowl, mix the egg yolks and sugar until well combined.
Pour the scalded milk over the yolk mixture and stir well.
Fold in the egg whites and flavor with nutmeg and vanilla or wine.
Set the mixture aside to cool slightly.
Caramel and bake
In a baking dish on the stove, melt 1½ cups of sugar over low heat, stirring constantly to prevent burning.
Once melted, pour the custard mixture into the dish with the caramel.
Bake in a slow oven at 300°F (150°C) until firm.
Cool and serve
Allow to cool completely, then turn out onto a flat platter to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set on heating, giving the custard its firm structure.
- Milk
- Provides the liquid base that the eggs set into a smooth custard.
- Sugar
- Sweetens the custard and melts into a brown caramel that coats the dish.
The step that matters
Bake in a slow oven until just firm. Egg proteins set gently at moderate heat. If the custard overheats, the proteins tighten too far, causing curdling and watery separation, so it should be removed once just firm.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, egg, sugar, vanilla):
- Cinnamonfits better
- Nutmegthe original
- Clovefits less well
- Peppermintfits less well
Fit is the average pairing score against milk, egg, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
