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 and a smooth, creamy texture.
- Cream
- Adds fat for a smooth, rich texture that resists ice crystals.
- Sugar
- Lowers the freezing point and adds sweetness, keeping the ice cream scoopable.
- Milk
- Provides the liquid base and dairy solids that form the custard.
- Coffee
- Supplies the main flavour of the ice cream.
The step that matters
Combine the egg mixture with the milk mixture to make a custard. Egg yolks thicken when gently heated but can scramble if the hot milk is added too quickly or the mixture overheats. Adding the hot liquid slowly while whisking keeps the custard smooth.
