It doesn’t look like much at first, this soup. The palest green possible, almost white in colour. Poured into a white bowl you’ll hardly realize it’s there. So why am I making such a fuss over this soup you might wonder. Because it’s worth it. I want you to taste it. The velvety smooth texture and the subtle flavours of leeks, potato, cream and white pepper. You can’t help but think “This one of the best soups I’ve ever had”. It is one of the highlights from the french cuisine. Some people serve it warm, but cooled is the traditional French way. I decorate this simple, sumptuous classic with onion sprouts and a light grating of nutmeg.
6-8 medium sized potatoes, peeled and quartered.
4 tbsp butter
4 cups chicken broth
2 tsp salt
3 tsp ground white pepper
1.5 cups heavy cream
Green onion sprouts
Boil the diced potatoes in salted water until just tender. Drain and put aside.
Cut off the dark green part of the leeks. You can discard them, or save them if you are planning on making a broth. For this soup, you only need the white and light green parts. Slice the leeks in half, lengthwise. Rinse to remove any dirt. Cut the leeks in 1” pieces. Sauté them lightly in the butter in a sauce pan for a few minutes. Add the chicken broth.
Once the broth comes to a boil, lower the heat, and let it simmer until the leeks are soft, 10-15 minutes. Add the potatoes, salt and the freshly ground white pepper (it might seem like a lot, but it’s important to taste the white pepper). Let simmer for another 5 minutes before transferring the soup into a blender. Blend until smooth. You might need to do it in two parts. Pour the soup through a sieve, pushing it through with a soup spoon. It will give the soup the extra smooth, velvety texture. Taste it and add more salt or pepper if needed. Let it cool and keep it in the fridge. 30 min before serving, move it to the counter to warm up slightly and stir in the cream. Makes 6 appetizer size servings.
