What each ingredient does
- Sugar
- Sweetens the punch and lowers its freezing point, keeping the frozen mixture softer and easier to scoop.
- Lemon juice
- Provides sharp acidity and bright citrus aroma that balance the sweetness.
The step that matters
Dissolve the sugar completely. Undissolved sugar crystals stay gritty and can settle in the bowl. Stirring the sugar fully into the hot water gives a smooth, evenly sweetened mixture that freezes uniformly.
