What each ingredient does
- Lemons
- Supply the juice that gives the lemonade its sharp, sour flavour and bright aroma.
- White sugar
- Adds sweetness that balances the sourness of the lemon juice.
- Water
- Makes up most of the drink and carries the dissolved sugar and lemon flavour.
The step that matters
Adding the sugar to the lemon juice. Sugar dissolves more readily in warm or hot liquid than in cold, so using boiling water or stirring well helps keep the sugar from settling at the bottom of the drink.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
