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 ↓
Ice Cream Without a Freezer
Ingredients
Directions
Make the custard
Beat the yolks of 8 eggs until light.
Stir in 4 cups of sugar.
Gradually add 1 quart of heated milk while beating continuously.
Fold in the beaten egg whites until well combined.
Boil the mixture in a pail set inside another with hot water for about 15 minutes, stirring steadily until thickened like custard.
Pour into a bowl to cool completely.
Once cool, beat in 3 pints of rich sweet cream and 5 teaspoons of vanilla or your preferred flavoring.
Freeze and finish
Transfer to a pail with a close-fitting cover.
Pack with ¾ ice and ¼ rock salt.
Beat the custard for 5 minutes.
Cover with the lid.
Add more ice and salt on top.
Cover with a thick mat or blanket.
Let sit for 1 hour.
Uncover.
Scrape the frozen custard from the sides and bottom.
Beat again until smooth and half-congealed.

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 during cooking.
- Egg whites
- Add airiness to the custard mixture, lightening its texture.
- Sugar
- Sweetens the custard and lowers its freezing point for a softer texture.
- Rich milk
- Forms the liquid base that the custard cooks and thickens in.
- Rich sweet cream
- Adds fat that makes the frozen custard smooth and creamy.
The step that matters
Boiling the custard until thickened. Egg yolks must be heated gently while stirred, or they can scramble and curdle. Stopping when the custard coats a spoon ensures it thickens properly before freezing.
