Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon juice
- Adds sharp acidity that balances the sweetness and brightens the flavour.
- Orange juice
- Adds fruity sweetness and liquid that freezes into the ice's body.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice softer.
- Bananas
- Sieved, they add body, sweetness and a smooth, creamy texture.
- Peaches
- Sieved, they add fruit flavour, sweetness and body to the ice.
The step that matters
Add the fruit once the mixture begins to freeze. Adding the juices and sieved fruit only after ice crystals start to form lets them mix evenly through the partly frozen base. Added too early, they can dilute the mixture and slow freezing; added too late, they stay in lumps and the texture turns uneven.
