Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon water ice
- Provides the frozen base and sweet citrus flavour that the spirits are mixed into.
- Champagne
- Adds liquid and bright effervescent flavour to the frozen base.
- Jamaica rum
- Adds liquid and a rich, spirited flavour; alcohol also keeps the punch softer when frozen.
- Maraschino liqueur
- Adds sweetness and a distinct cherry-almond aroma.
The step that matters
Freeze for 4 to 5 hours after packing. Alcohol lowers the freezing point, so the punch stays softer than plain ice. Packing the container tightly and covering it limits air exposure, which helps prevent ice crystals and freezer odours from spoiling the texture and flavour.
