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
Prepare
In a double boiler, heat the milk until scalded.
In a small bowl, moisten the cornstarch with a little cold water.
In another bowl, beat the egg yolks with the sugar until light.
Make the custard
Add the moistened cornstarch to the scalded milk, stirring constantly until smooth and thick.
Add the egg mixture to the cornstarch mixture and remove from heat.
Finish
Once cool, stir in the grated orange rind and orange juice.
Add vanilla extract if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the cornstarch thickens and the yolks enrich.
- Cornstarch
- Thickens the filling as its starch grains swell and gel in hot liquid.
- Egg yolks
- Thicken and enrich the filling, adding richness and a smooth, custard-like body.
- Sugar
- Adds sweetness and softens the set of the filling.
- Orange juice
- Adds bright acidity and citrus flavour.
- Orange rind
- Contributes concentrated citrus aroma from the oils in the peel.
The step that matters
Adding the egg mixture to the cornstarch mixture. Egg yolks scramble when they meet very hot liquid. Stirring steadily and removing the pan from heat as the eggs go in keeps the custard smooth rather than grainy.
