Ingredients

500 gpotatoes
1000 mlvegetable stock
200 mlheavy cream
30 gbutter
5 gsalt
2 gwhite pepper
15 gfresh chives
Instructions
1PREPARE THE LEEKS: Slice the white and pale green parts of the leeks into thin rounds, discarding the dark green tops. Rinse thoroughly under cold running water, separating the layers to remove any trapped soil or sand. Pat dry with paper towels. Reserve a small amount of finely sliced leeks for garnish.
2PREPARE THE POTATOES: Peel and dice the potatoes into uniform 2cm cubes to ensure even cooking. Place the diced potatoes in a bowl of cold water to prevent discoloration and to remove excess starch, which will help create a silkier final texture.
3SAUTÉ THE LEEKS: Melt the butter in a large heavy-bottomed pot over medium heat. Add the prepared leeks and cook gently for 8-10 minutes, stirring occasionally, until they become soft and translucent but not browned. This step builds flavor by releasing the leeks' natural sweetness without caramelizing them.
4COOK THE SOUP: Add the drained potatoes to the pot and stir well to combine with the leeks. Pour in the vegetable stock and bring to a gentle boil over medium-high heat. Season with salt and white pepper, then reduce heat to medium-low and simmer uncovered for 20-25 minutes until the potatoes are completely tender and fall apart easily with a fork.
5BLEND UNTIL SMOOTH: Remove the pot from heat and let cool slightly for 2-3 minutes. Using an immersion blender, puree the soup directly in the pot until completely smooth and silky, working in batches if necessary. For an ultra-fine texture, pass the soup through a fine-mesh sieve, pressing gently with the back of a ladle. Stir in the heavy cream until fully incorporated.
6CHILL THOROUGHLY: Pour the soup into a container and refrigerate for at least 4 hours, preferably overnight, until completely chilled. This resting period allows the flavors to meld and develop. Just before serving, adjust seasoning if needed with additional salt and white pepper. Ladle into chilled bowls, garnish with reserved sliced leeks and fresh chives, and serve immediately.
