For the chive salt, first wash and dry the chives and cut into 3 mm wide rolls. Place in a Thermomix with about 100 g sea salt and blend well. The salt should turn green and the chives should be chopped whole.
Put the wet salt on a baking tray covered with baking paper and dry at 50 °C hot air with the handle of a wooden spoon clamped in for about 1 hour.
Blend the chive salt again with the remaining sea salt in the again dried blender.
