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
Make the custard
Boil 3 pints of milk in a double boiler.
Beat yolks and whites of eggs separately.
Mix yolks with remaining pint of milk and stir into boiling milk.
Boil for 2 minutes, then remove from heat.
Add sugar and let it dissolve.
Strain through a cloth and cool.
Add cream and vanilla, then refrigerate until needed.
Freeze
Prepare ice by pounding it until small.
Pack ice and salt around the freezer, using ¾ ice and ¼ salt.
Pour custard into the freezer, filling ⅔ full, and replace the cover.
Begin turning the freezer to churn the ice cream.

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 and supplies milk solids for body and a rich, dairy flavour.
- Eggs
- Egg yolks thicken the custard as they heat and help bind the base smoothly.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer and smoother.
- Cream
- Adds fat, which makes the frozen texture creamy and less icy.
- Vanilla
- Adds aroma and rounds out the flavour of the dairy base.
The step that matters
Boil for 2 minutes, then remove from heat. Egg yolks thicken the custard as they heat, but overheating can scramble them into lumps. Stopping at the set time keeps the custard smooth before straining.
