Potato and leek soup is a classic and comforting dish that's perfect for cooler weather. This recipe combines the gentle sweetness of leeks with the heartiness of potatoes to create a deliciously creamy soup. The addition of vegetable broth, milk, and light sour cream adds depth and richness without being overly heavy.

Instructions:

1. Prepare the Leeks:
- Begin by trimming off the dark green tops and roots of the leeks. Slice them in half lengthwise and rinse thoroughly under cold running water to remove any grit or dirt. Once cleaned, chop the leeks into thin slices.

2. Cook the Leeks:
- In a large pot, heat the butter and olive oil over medium heat. Add the chopped leeks and cook, stirring occasionally, until they become soft and translucent, about 5-7 minutes. Be sure not to let them brown.

3. Add the Potatoes:
- Peel and dice the potatoes into small chunks. Add them to the pot with the softened leeks. Stir to combine and cook for another 2-3 minutes.

4. Add the Broth:
- Pour in the vegetable broth, followed by just enough water to cover the potatoes and leeks. Bring the mixture to a boil, then reduce the heat and let it simmer for about 20 minutes, or until the potatoes are tender.

5. Blend the Soup:
- Once the potatoes are tender, use an immersion blender to puree the soup until smooth. Alternatively, you can transfer the soup in batches to a regular blender. Be cautious when blending hot liquids.

6. Add Milk and Sour Cream:
- Return the pureed soup to the pot if you've used a regular blender. Stir in the milk and the light sour cream until fully incorporated. Warm the soup over low heat until heated through, but do not let it boil.

7. Season:
- Taste the soup and season with salt and black pepper to your preference.

8. Serve:
- Ladle the hot potato and leek soup into bowls. Optionally, garnish with chopped chives, a drizzle of olive oil, or a dollop of sour cream. Serve hot with crusty bread on the side.

With just a few simple ingredients and some easy steps, you can make a satisfying bowl of potato and leek soup. It's a versatile recipe that you can customize to your taste, and it's sure to become a favorite in your household. Enjoy the warm, creamy flavors and feel-good factor of this delicious soup!
