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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
In a saucepan, heat the milk and sugar until warm.
In a bowl, whisk together the eggs, vanilla, and salt.
Slowly add the warm milk mixture to the egg mixture, stirring constantly.
Bake and check
Butter small cups and place them in a shallow pan filled with hot water.
Pour the custard mixture into the cups, filling them nearly to the top.
Keep the water boiling until the custards are set, about 30-40 minutes.
Check for doneness by inserting a teaspoon handle into the center; it should come out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a firm, sliceable texture as they cook.
- Milk
- Provides the liquid base and moisture that gives the custard its smooth body.
- Sugar
- Sweetens the custard and adds flavor to the milk base.
The step that matters
Slowly add the warm milk mixture to the egg mixture, stirring constantly.. Adding hot liquid to eggs too quickly can scramble them. Gradual addition with constant stirring gently raises the egg temperature so the custard stays smooth.
