What each ingredient does
- Loaf sugar
- Provides sweetness and forms the powder base that carries the lemon flavour.
- Tartaric acid
- Supplies sourness that gives the lemonade its tart bite.
- Lemon
- Its rind contributes fragrant citrus oils that flavour the sugar.
The step that matters
Rub the rind on the sugar until fragrant. Lemon oil sits in the peel, and rubbing it into the sugar releases that aroma into the crystals. Stopping early leaves the flavour weak, while the sugar must stay dry so the powder keeps well in the sealed bottle.
