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 ↓
Orange Filling for Cake
Ingredients
Directions
Make the custard
In a double boiler, heat the milk until scalded.
Moisten the cornstarch with a little cold water and add it to the scalded milk.
Stir constantly until the mixture is smooth and thick.
Beat the egg yolks with the sugar until light and fluffy.
Add the egg mixture to the cornstarch mixture and remove from heat.
Flavor and finish
Once cool, stir in the grated orange rind and orange juice.
Add vanilla for flavor if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and add richness and a smooth, custardy texture.
- Cornstarch
- Thickens the hot milk into a smooth, stable filling as it heats.
- Milk
- Forms the liquid base that the cornstarch and yolks thicken.
- Sugar
- Sweetens the filling and helps the yolks whip to a light, fluffy texture.
- Orange rind
- Adds bright citrus aroma and flavor to the filling.
- Orange juice
- Adds citrus acidity and fresh orange flavor to the filling.
The step that matters
Add the egg mixture to the cornstarch mixture and remove from heat. Egg yolks can scramble if they meet very hot liquid too quickly. Stirring constantly and removing the pan from heat keeps the custard smooth while the yolks thicken it gently.
