From plant to use

Decoction

Simmering roots, bark and seeds so they release their flavour and compounds.

Level
Easy
Ratio
About 1 tablespoon of dried, coarsely cut material per 300–500 ml of cold water.
Time
Bring to the boil and simmer gently for 15–30 minutes with the lid on. Mushrooms often longer.
Shelf life
Covered in the fridge for 1–2 days.

Hard plant parts give up little in a short infusion. That is why many traditions gently boil roots, bark, seeds and berries: a decoction. Think of ginger root, cinnamon bark and the herbal formulas of Ayurveda and traditional Chinese medicine.

Suited to

Roots, rhizomes, bark, seeds, dried berries and mushrooms.

Step by step

  1. Cut or crack the material coarsely to increase its surface.
  2. Put it in cold water and bring slowly to the boil.
  3. Turn the heat down, cover the pan and let it simmer gently.
  4. Strain, and top up with hot water to the original volume if you like.

Tips

  • Roots and leaves together? Simmer the roots first, then add the leaves once the heat is off and let them steep for another 5–10 minutes.
  • Soak the material in cold water for an hour beforehand for a fuller flavour.
