Sugar and lemon 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
Provides the starch and body that give the drink its mild, cloudy character.
Sliced figs
Add natural sweetness and a soft, fruity flavour to the liquid.
Sugar
Adds sweetness to balance the flavour of the barley and figs.

The step that matters

Boil down to 2 pints. Boiling the barley in 4 pints of water and reducing it concentrates the liquid. Stopping at the right volume sets the strength of the final drink, so the measure matters.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (barley, fig, sugar):

  1. Vanillafits better
  2. Pearfits better
  3. Raisinfits better
  4. Lemonthe original

Fit is the average pairing score against barley, fig, sugar. Candidates are from the same food group and used in at least 100 recipes.
