Instead of buying a new spice grinder every time you run out, you can open it, add spices, and reuse it.
The first thing you need to do is boil a small amount of water and fill it into a container of a suitable size.
Place the mill in a plastic bag and immerse it in boiling water for about 30 seconds.
After you remove the device from the hot water, wrap the lid in a towel and unscrew the top.
By the way, you can heat the mechanism with the lid not only by dipping it in boiling water, but also by heating it with hot air from a hair dryer.
Now all that's left to do is fill the jar with a funnel and add pepper mixture, sea salt or any other spices you like.
All that remains is to place the grinding mechanism together with the lid in its rightful place.
To use a newly filled mill, you need to act as usual: remove the lid and, holding the grinding mechanism in one hand, rotate the mill container with spices.
