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 ↓
Vanilla Ice Cream
Ingredients
Directions
Make the custard
In a saucepan, combine milk, eggs, sugar, and dissolved cornstarch.
Cook over medium heat, stirring constantly, until it thickens like custard.
Remove from heat and let cool.
Finish and freeze
Once cooled, stir in vanilla extract.
Whip the heavy cream until soft peaks form and fold it into the mixture just before freezing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard base and add richness as they cook.
- Cornstarch
- Thickens the custard base so it sets smoothly when cooked.
- Heavy cream
- Adds fat and whipped volume, giving a lighter, creamier texture.
- Sugar
- Sweetens the base and softens the texture of the frozen ice cream.
The step that matters
Cooking the custard until it thickens. Stirring constantly over medium heat keeps the eggs and starch from scorching or lumping. The mixture must thicken like custard so the egg proteins and starch set the base, which gives a smooth, stable texture once frozen.
