Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sage, burnet, balm and sorrel
Provide the main herbal aroma and flavour of the tea.
Lemon
Adds acidity that brightens the herbal flavours.
Boiling water
Extracts flavour and aroma from the herbs as it steeps.
Sugar
Adds sweetness to balance the herbs and lemon.

The step that matters

Cover the jug. Covering the jug traps the warm steam, which holds the volatile aromatic compounds from the herbs. Leaving it uncovered lets much of that aroma escape, leaving a weaker-tasting infusion.

Flavor stand-ins for the sorrel

  4. Sorrelthe original

Fit is the average pairing score against sage, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
