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

What each ingredient does

Pearl barley
Its starch and flavour leach into the water, giving the tea body and a mild grain taste.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.
Sugar
Adds sweetness, adjusted to the drinker's taste.

The step that matters

Keep the water topped up while boiling. Long simmering concentrates the liquid and can scorch the barley on the bottom of the pot. Adding water keeps enough liquid for the starch and flavour to extract evenly and keeps the tea from tasting burnt.

Swap the lemon

How well each one fits the dish's main ingredients (barley, sugar):
