Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrow-root
- Thickens the water into a light, smooth, slightly silky drink as it heats.
- Loaf sugar
- Adds sweetness to balance the lemon flavour.
- Lemon peel
- Infuses the water with aromatic lemon oils while it boils.
- Lemon juice
- Adds fresh acidity and brightness just before drinking.
The step that matters
Stir the arrow-root mixture into the boiling water. Arrowroot starch thickens when heated and can clump if added unevenly. Stirring well while pouring the hot lemon water over the starch slurry disperses the granules so the drink turns smooth rather than lumpy.
