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
Beat the egg yolks with the sugar until very light.
Scald the milk in a saucepan and flavor it with the powdered vanilla.
Once the milk is scalded, let it cool slightly, then stir it into the egg mixture.
Place the mixture over boiling water and stir constantly until it thickens slightly.
Remove from heat and mix in the soaked gelatin until dissolved.
Freeze
Cool the custard completely before placing it in the freezer.
Stir the mixture almost constantly in the freezer until it begins to set.
Gently fold in the whipped cream and stir for 2-3 minutes.
Transfer to a mold and return it to ice and salt for further chilling.

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 and add richness as they set with gentle heat.
- Rich milk
- Provides the liquid base and fat that give the ice cream its creamy body.
- Sugar
- Sweetens the base and lowers the freezing point so the mixture stays softer.
- Whipped cream
- Adds air and fat, making the frozen texture lighter and smoother.
- Gelatin
- Stabilises the custard so it holds a smooth, firm texture when frozen.
The step that matters
Thickening the custard over boiling water. Stirring constantly keeps the egg yolks from scrambling on the hot surface. Gentle heat thickens the custard evenly, which gives the smooth texture the ice cream needs.
