Take the green tops of 4 green onions and slice them very thin lengthwise. Place them in ice-cold water and set aside to curl naturally.
In a pot, melt butter. Add the white part of the 4 green onions (chopped), 3 garlic cloves (chopped), salt, black pepper, and a pinch of cayenne. Sauté until fragrant and softened.
Add 4 cups of chicken stock and 3 potatoes (peeled and cut into even sized pieces). Bring to a simmer and cook until the potatoes are fully tender.
Once the potatoes are soft, add 1 cup cream and blend everything until smooth and velvety. Taste and adjust seasoning if needed.
Serve hot and garnish with a drizzle of olive oil, freshly cracked black pepper, the green onion curls, and a spoon of sour cream.
