Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl barley
- Releases starch and grain flavour into the water, giving the drink light body and a mild taste.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Sugar
- Adds sweetness to balance the tart lemon.
The step that matters
Covering the mixture while it stands. Keeping the lid on holds in heat and steam, so the barley keeps releasing starch and flavour into the water over the full three hours. Uncovering it lets the liquid cool and the infusion weaken.
Swap the lemon
