The flavor team

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.

    Shared aroma: beta-damascenone (apple, rose).

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

Pearl barley
Gives the drink its body and mild, starchy flavour as it steeps.
Lemon
Its peel and juice add aroma and acidity that brighten the drink.
Sugar
Adds sweetness that balances the lemon's acidity.

The step that matters

Blanch the barley. Boiling the barley briefly in cold water, then discarding that water, removes surface starch and dust before steeping. This keeps the finished drink clearer and cleaner in taste.

Swap the lemon

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

  1. Vanillafits better
  2. Figfits better
  3. Raisinfits better
