1. Place the strawberries and herbs in a saucepan (possibly with a little water, about 25 ml) and bring to a boil.
2. Add the Zùsto & the Agar-Agar and simmer for 10 minutes.
3. Pour the jam into glass jars, close the jars and store them upside down. Allow to cool to room temperature.
4. Then keep the jam in a cool place.

Note: by adding Zùsto, the jam contains much less sugar than ordinary jam, but it also doesn’t keep for as long.
