Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Frozen Custard
Ingredients
Directions
Make the custard
In a double boiler, heat 1½ quarts of cream with the sugar, stirring well.
Beat the egg yolks until light, then mix in the remaining ½ pint of cold cream.
Once the cream in the boiler is boiling, stir in the egg and cream mixture.
Stir continuously until the mixture thickens, then remove from heat.
Finish and freeze
When cool, add the vanilla and freeze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides fat and richness, giving the frozen custard its smooth, creamy body.
- Egg yolks
- Their proteins set as they heat, thickening the custard and adding richness.
- Sugar
- Adds sweetness and keeps the frozen texture softer by lowering the freezing point.
- Vanilla
- Adds aroma and flavour to the finished custard.
The step that matters
Thicken the custard gently. Stir continuously until the mixture thickens, then remove it from the heat promptly. Egg yolk proteins set as they warm, and if the mixture overheats it can curdle or scramble, leaving a grainy texture instead of a smooth custard.
