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 ↓
Barley Water
Ingredients
Directions
Prepare the barley
Put the barley into a saucepan with 1 pint of cold water.
Bring it to a boil, then strain the water as it is unwholesome.
Add another pint of cold water to the barley and bring it to a boil again.
Simmer and flavour
Let it simmer for 10 minutes.
Strain it into a jug, add a few drops of lemon juice and a little sugar, but do not make it too sweet.
Let it cool before drinking.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Keen, robinson's patent barley
- Provides the main body and mild flavour of the drink as it simmers out of the grain.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Sugar
- Adds sweetness, added to taste so the drink stays mild.
The step that matters
Straining off the first water. Boiling the barley first and discarding that water removes impurities and bitter flavours from the grain before the final brew, so the drink tastes clean.
Swap the lemon
How well each one fits the dish's main ingredients (barley, sugar):
- Vanillafits better
- Figfits better
- Raisinfits better
- Lemonthe original
Fit is the average pairing score against barley, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
