Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Powdered sugar
- Dissolves into the water to sweeten the punch.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the flavour.
- Lemon rind
- Contributes aromatic citrus oils that scent the punch.
- Kirsch
- Adds cherry-like aroma and alcoholic flavour, and lowers the freezing point so the mixture stays slushy.
- Cold water
- Provides the liquid base that freezes into the punch's icy texture.
The step that matters
Detaching the frozen mixture from the freezer sides. Frozen mixture sticks to the cold walls and forms ice crystals; scraping it free and stirring again keeps the texture smooth and slushy rather than solid. Keeping ice and salt out of the mixture stops it from becoming salty or diluted.
