What each ingredient does
- Arrow-root
- Thickens the water into a light, clear, gel-like drink as it heats.
- White sugar
- Adds sweetness to balance the lemon peel and mild thickened water.
- Lemon peel
- Adds bright citrus aroma and flavour from the oils in the peel.
The step that matters
Boiling the arrow-root mixture. Arrow-root starch only thickens fully once it reaches a boil, so the liquid must be kept boiling for the full time to reach its proper texture.
