Dry nasturtium
You can dry the leaves and flowers of the nasturtium to use them for seasoning or to prepare tea. Drink two to three cups of this tea daily to prevent catching a cold. You can also use it to support the treatment of cystitis or infections of the upper respiratory tract.

The dried seeds are not suitable for tea, but they are good for flavoring food. You can very well crush the seeds in a mortar or grind them in a spice grinder. However, make sure that the seeds are really well dried so that they don’t start to get moldy. They’re also easier to grind up.
Pickle the nasturtium
The unopened buds or the unripe seeds of the nasturtium are suitable for pickling in vinegar. Boil both in a broth of vinegar, water, and salt and fill the hot mixture into twist-off glasses. Stored in a cool and dark place, these “fake capers” can be kept for a few months.
You can pickle the blossoms of the nasturtium in a mild fruit vinegar. Pour both into a wide-necked bottle. The vinegar must completely cover the blossoms, otherwise, they could start to get moldy.
Leave the vinegar to mature in a dark place for about four weeks, shaking the bottle once a day. After four weeks, strain the vinegar.
You can produce flower oil with the help of high-quality vegetable oil. It is best to use a tasteless, cold-pressed oil, such as sunflower or rapeseed oil. In contrast to vinegar, however, the oil must be steeped in a warm and bright place.
