We travelled along the Portugese coast. We stayed over night high above the sea in the West Algarve. There was a scent in the air, familiar but I couldn’t name it. And I couldn’t find a plant with this scent. It was just in the air – everywhere. Going to a beach restaurant there were many dishes with coriander. That was it – coriander. I have learned something new: the national herb of Portugal is coriander.
