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 with Eggs
Ingredients
Directions
Make the custard
Cream the egg yolks and sugar together until light.
Heat the milk with the vanilla until boiling, then gradually stir it into the egg mixture, whisking briskly.
Place the mixture over hot water and stir constantly until it thickens slightly, but do not let it boil.
Remove from heat and stir in the soaked gelatin until dissolved.
Strain the custard into a bowl and let it cool completely before freezing.
Churn and set
Prepare your ice cream maker with ice and salt.
Pour the custard into the cylinder, pack with ice and salt, and churn steadily.
When the crank is difficult to turn, scrape down the cream from the sides and fold in the chilled whipped cream.
Close the cylinder and churn again until too stiff, then remove the dasher and smooth the ice cream.
Cover and pack with more salt and ice, then let it sit for 2 to 3 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set on gentle heat, and add richness.
- Milk
- Forms the liquid base of the custard that freezes into the ice cream.
- Sugar
- Sweetens the base and lowers the freezing point for a softer texture.
- Gelatine
- Adds body and helps the frozen ice cream hold a smooth, stable texture.
- Cream, whipped
- Adds air and fat, making the ice cream lighter and creamier.
The step that matters
Cooking the custard over hot water. If the egg yolk mixture boils, the eggs scramble and curdle. Gentle heat that only thickens it keeps the custard smooth.
