Beetroot with Yoghurt

This is a classic dish that adds vibrant colour to any mezze spread. When beetroot are in season you may come across the golden and stripy varieties. While not entirely traditional, a combination of these can make this dish even more startling. Nigella (or black onion seed) is an aromatic, charcoal-black seed similar to black sesame in shape. It is sprinkled on yoghurt and flatbreads, especially in Turkey.
