Iced cinnamon tea recipe:

Water (cold) – 1500 ml
Cinnamon (cinnamon stick) – 1 pc.
Carnation – 2 pcs

Orange peel – to taste
Nectarine (for serving at will) – 1 pc.
Orange juice – 100 ml
Orange (optional) – to taste

Pour cold water into a jug (of course, not from the tap).
Add tea leaves, orange zest, cloves, cinnamon stick.
