Shared aroma: coumarin (sweet, hay).

What each ingredient does
- Arrowroot
- Starch that thickens the liquid into a clear, glossy jelly as it heats.
- Lemon
- Adds acidity and aroma to the water as it steeps.
The step that matters
Stir the arrowroot paste into the hot water. Arrowroot must be mixed into a smooth paste with cold water first, otherwise it clumps when added to hot liquid. Starch granules swell and thicken only when heated, so the mixture needs to boil to set properly.
