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 as they heat and add richness and a smooth, custard-like structure.
- Cream
- Provides fat and richness, giving the ice cream a smooth, creamy body.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer and less icy.
- Butter
- Adds fat that coats the palate, giving a rich, smooth mouthfeel.
- Vanilla
- Contributes the main aroma and flavour of the ice cream.
The step that matters
Heat gently and stop at thickening. Egg yolks thicken the custard as they warm, but if the mixture boils they overcook and curdle, leaving the ice cream grainy. Low heat and removing it once it begins to thicken keeps it smooth.
