Melt the butter in a pan and cook the onion and leek for 5 minutes.
Add the garlic, potatoes, sea salt, pepper and nutmeg. Pour in the stock, stirring briskly. Simmer until the potatoes are soft, about 15 minutes.
Drop in the spinach, pushing it down until it wilts. Add the watercress, again pushing it into the soup until just wilted.
Whiz in a blender until very smooth. Reheat gently, pour into warm bowls and drizzle with yoghurt. Top with watercress sprigs.
