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 as it heats, giving the drink a light, smooth body.
White sugar
Adds sweetness that balances the sharpness of the lemon juice.
Lemon juice
Adds acidity and bright citrus aroma.

The step that matters

Pour in boiling water while stirring constantly. Arrowroot starch thickens quickly when hot. Constant stirring disperses it evenly so the drink thickens smoothly without lumps or clumps.
