What each ingredient does
- Arrow-root
- Thickens the water into a light, smooth drink as it heats.
- Loaf sugar
- Sweetens the drink, balancing the sharpness of the lemon.
- Lemon juice
- Adds fresh acidity and bright lemon aroma just before drinking.
The step that matters
Stirring the arrow-root mixture into the boiling water. Arrow-root starch thickens when heated but can clump if added as dry powder or stirred poorly. Mixing it first with cold water and stirring it into the hot liquid helps it disperse evenly and thicken smoothly.
