Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Arrowroot
Starch that thickens the liquid and gives a clear, glossy jelly when cooled.
Lemon peel
Infuses the water with aromatic citrus oils for a bright flavour.
Sugar
Adds sweetness to balance the lemon flavour.

The step that matters

Adding the dissolved arrowroot to the hot water. Arrowroot must be fully dispersed in cold liquid first, then stirred into the hot liquid and boiled. Stirring prevents lumps, and the heat swells the starch granules so the mixture thickens.
