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 ↓
California Ice Cream
Ingredients
Directions
Make the custard base
In a double boiler, heat the milk until boiling.
Beat the egg yolks until light, then add them to the boiling milk.
Stir in the flour and cook gently, avoiding curdling the eggs.
If using a vanilla bean, split it lengthwise and cook it in the milk, scraping the seeds into the mixture for flavor.
Remove from heat and let cool completely, preferably overnight.
Finish and freeze
When ready to freeze, mix in the double cream and remaining sugar until well combined.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the base and add richness as they set gently with heat.
- Flour
- Stabilises the base so it stays smooth and thick after cooking and cooling.
- Double cream
- Adds fat for a rich, smooth texture that resists iciness.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer.
- Whole milk
- Provides the liquid base that the eggs and flour thicken.
The step that matters
Cook gently after adding the eggs. High heat or fast boiling can scramble egg yolks and make the custard grainy or curdled. Gentle, steady heat lets the yolks thicken the milk smoothly, and the flour helps stabilise the mixture.
