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
Make the caramel
Combine 1 cup sugar with a little water in a saucepan. Cook until dark brown and thick.
Coat a mold with caramel and let harden, reserving 2‑3 tablespoons for custard flavoring.
Make the custard
Beat eggs, 5 teaspoons sugar, and vanilla extract together in a bowl.
Add milk, reserving about ½ cup, and mix in reserved caramel.
Pour milk mixture into a saucepan and heat to infuse flavor.
Combine heated milk with egg mixture and pour into mold.
Bake and test
Place mold in a water bath and bake until set.
Test doneness by inserting a knife; 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 structure as they coagulate with heat.
- Milk
- Provides the liquid base and creamy, tender texture of the custard.
- Sugar
- Sweetens the custard and, when cooked dark, forms the caramel that flavors the dish.
- Vanilla extract
- Adds aromatic flavor to the egg and milk mixture.
The step that matters
Bake in a water bath until just set. Water bath moderates oven heat so the eggs set gently; overheating causes the custard to curdle or turn rubbery and watery.
