From plant to use

Tea (infusion)

Hot water poured over leaves and flowers: the simplest and most widely used preparation.

Herbs prepared this way (350)
Level
Easy
Ratio
1–2 teaspoons of dried herb (or 2–3 teaspoons fresh) per 250 ml cup.
Time
Steep 5–10 minutes, covered; flowers a little shorter, leaves a little longer.
Shelf life
Drink fresh, or keep covered in the fridge for up to 24 hours. Store dried herbs airtight, dark and dry, and use within a year.

For an infusion you pour hot water over soft plant parts such as leaves, flowers and fine herbs and let them steep, covered. Flavour and aroma pass into the water without long heating. Almost every tradition knows this form, from European herbal teas and South American mate to North African mint tea.

Suited to

Leaves, flowers, soft stems and aromatic herbs such as mint, chamomile, lemon balm and linden flowers.

Step by step

  1. Bring fresh water to the boil and let it cool briefly to about 90–95 °C. Green tea and mate do better at 70–80 °C.
  2. Put the herb in the pot or filter and pour the water over it.
  3. Cover, so the volatile aromas do not escape.
  4. Steep, strain and drink warm, or let it cool for iced tea.

Tips

  • Cold brew: leave dried herbs in cold water in the fridge for 6–12 hours. The taste is softer; drink it within a day.
  • For your own blend, combine one distinct flavour (mint, lemongrass) with milder herbs.
