1. Soak sesame seeds in water for about 8 hours.
2. Drain the soaked sesame well.
3. Pour salt into an unoiled pan and roast slowly until it turns slightly grayish. Pour the salt into a bowl.
4. Add the sesame seeds to the same pan and slowly roast them again until they reach a slightly brownish color. Add the sesame seeds to the bowl with the salt.
5. Also lightly roast the nettle seeds in the pan. 
6. Crush the salt-sesame mixture slightly with a mixer or in a mortar.
7. Add the nettle seeds to the mixture and mix everything well.
8. Pour into a glass and enjoy.

Tip: It's better to make smaller quantities as sesame contains natural oils and can go rancid after a few months. In addition, the spice should not be heated, but is only intended for finished dishes.
