Peel and dice the onion, peel the potatoes and cut into pieces.
Sweat the onion in a pan with the butter until it is golden yellow. Pour in the broth and add the potatoes and wild garlic, leaving four leaves of wild garlic for the garnish. Add salt and pepper to taste and simmer slowly until the potatoes are tender.
Then mix the soup with a hand blender and finally stir in the cream.
Bring to the boil again briefly and serve hot, garnished with the wild garlic.
