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 soluble compounds gradually release into the water, giving the drink body and a mild grain flavour.
- White sugar
- Adds sweetness that balances the tart lemon and the earthy barley.
- Lemon rind
- Its aromatic oils flavour the water, adding bright citrus aroma.
The step that matters
Let it stand for 8 to 10 hours. Flavour and body come from slow steeping, not heat. Too short a steep leaves the drink weak and thin, while the barley and rind need the full time to release their compounds into the water.
