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 the eggs until light, then stir in the sugar.
Gradually add the heated milk while beating continuously.
Fold in the beaten egg whites until well combined.
Boil the mixture in a double boiler for about 15 minutes, stirring steadily until thickened like custard.
Pour into a bowl and let cool completely.
Once cool, mix in the sweet cream and vanilla or preferred flavoring.
Freeze in the pail
Transfer to a pail with a close-fitting cover and pack with ice and rock salt (3 parts ice to 1 part salt).
Before sealing, beat the mixture for 5 minutes.
Cover with the lid, add more ice and salt, and insulate with a blanket.
Let it sit for 1 hour, then scrape the sides and bottom of the pail to mix the frozen custard.
Beat again until smooth and half-congealed.
Cover and let it sit for 5-6 hours, replenishing ice and salt as needed.

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 air and lightness to the custard mixture before it is cooked.
- Sugar
- Sweetens the base and softens the texture of the frozen cream.
- Milk
- Forms the liquid base that the eggs thicken into custard.
- Sweet cream
- Adds fat and richness, giving the finished ice cream a smooth, creamy mouthfeel.
The step that matters
Cooking the custard to thickness. Egg yolks thicken as they heat, but if the custard boils too hard or is overheated, the eggs can curdle and turn grainy. Steady, gentle stirring in the double boiler keeps it smooth before cooling and freezing.
