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 ↓
Plain Ice Cream
Ingredients
Directions
Make the custard
In a double boiler, cook the milk until boiling.
In a bowl, beat the eggs, flour, and part of the sugar to form a light batter.
Stir the batter into the boiling milk and cook for 20 minutes, stirring often.
Finish and freeze
Once cooled, beat in the remaining sugar and cream, then add vanilla extract.
Freeze the mixture until solid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set with heat, giving it body and structure.
- Flour
- Stabilises the thickened base so it stays smooth and does not weep when cooked.
- Milk
- Forms the liquid base that the eggs and flour thicken into a custard.
- Cream
- Adds fat, richness, and a smooth, creamy texture to the frozen ice cream.
- Granulated sugar
- Adds sweetness and softens the frozen texture, keeping it from freezing rock hard.
The step that matters
Cooking the batter into the boiling milk. Egg proteins can curdle or form lumps if the mixture overheats or stops being stirred. Stirring often keeps the thickened custard smooth and prevents scorching on the base of the pan.
