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 ↓
Custard Pie
Ingredients
Directions
Make the custard
Beat the eggs slightly, then add the sugar and salt.
Stir in the hot milk and strain the mixture.
Cool the mixture, then add the vanilla.
Bake
Pour the mixture into a pie plate lined with pastry.
Bake in a preheated oven at 450°F (200°C) for 10 minutes, then reduce the temperature to 325°F (150°C) and bake until the custard is firm.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Eggs
- Set the custard into a firm, sliceable structure as they cook.
- Sugar
- Sweetens the custard and adds body to its texture.
- Hot milk
- Forms the liquid base that the eggs thicken as it bakes.
- Vanilla
- Adds aroma and a rounded flavour to the custard.
The step that matters
Bake until the custard is firm. Egg proteins set gradually as the custard heats. Baking too long or at too high a heat can curdle the custard and make it watery or grainy, so it should be removed once just set.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, milk, vanilla):
- Cinnamonfits better
- Nutmegthe original
- Clovefits less well
- Peppermintfits less well
Fit is the average pairing score against egg, sugar, milk, vanilla. Candidates are from the same food group and used in at least 100 recipes.
