Serves: 4Hands-on: 20 minutesTotal: 2 hours 20 minutesDifficulty: Easy

- In a large saucepan, melt the butter on low heat. Add the diced onion and cook slowly, stirring often, for 5 minutes. Then add the leeks (only the white parts, cut in very thin slices), and cook slowly for another 5 minutes. Add the potatoes, salt, and pepper, and stir well. Add the chicken stock, bring to a boil over high heat, then reduce to a simmer. Add the milk, stir well, and simmer for 30 minutes over very low heat.
- Pour into a blender and process until very smooth. Pour the mixture into a serving bowl, and let it cool at room temperature for about 30 minutes. You can then add the cream. Stir well, and put in the refrigerator for 1 hour.
