Why it works: Barley and lemon work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 484 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl barley
- Releases starch as it simmers, giving the liquid a light body and soft texture.
- Lemon rind
- Adds fragrant citrus oils and a fresh, slightly sharp aroma to the drink.
- Sugar
- Adds sweetness, balancing the lemon and the plain barley flavor.
The step that matters
Boiling the barley in fresh water and discarding both waters. The first wash and short boil remove surface dust and loose impurities from the grain. Discarding that water before adding the fresh boiling water keeps the final drink clean-tasting and clear.
