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 ↓
Ices and Ice Cream
Ingredients
Directions
Make the custard
Boil 3 pints of milk.
Beat the egg yolks.
Beat the egg whites.
Mix the yolks with the remaining pint of milk. Stir the mixture into the boiling milk.
Boil for 2 minutes. Remove from heat.
Add sugar and let it dissolve.
Strain through a crash towel.
Cool the mixture.
Add cream and vanilla.
Set the custard and unwhipped egg whites in a cool place.
Prepare the freezer
Prepare ice by pounding it in a coarse coffee sack until small.
Pack the freezer with layers of ice and salt, starting and ending with ice.
Pour the custard into the freezer.
Add the whipped egg whites.
Freeze
Turn the freezer for 10 minutes.
Pack down the ice and drain water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard and enrich it, while whipped whites lighten the frozen texture.
- Milk
- Forms the liquid base of the custard that freezes into the ice cream.
- Sugar
- Sweetens the custard and lowers its freezing point, keeping the ice cream soft and scoopable.
- Cream
- Adds fat, which makes the frozen ice cream smooth and rich rather than icy.
- Vanilla
- Adds aroma and flavour to the custard.
The step that matters
Stir the yolks into the milk before boiling. Adding hot milk to yolks slowly, then returning it to heat, keeps the eggs from scrambling. Boiling the custard afterward thickens it evenly.
