Finely grate half a red cabbage. Add the flor de sal, coriander grains, cinnamon, oil and vinegar.
If you have time, to enhance the aroma you can lightly grill the coriander grains in a frying pan over medium heat for 1-2 minutes, without adding fat.
Stir, cover, and let marinate for at least an hour.
Grind some pepper before serving and sprinkle with parsley. Serve cold or at room temperature.
