Potato Soup with Leeks, Blood Sausage, and Parsley

• large leeks 2
• butter 3 tablespoons (40g)
• medium celery ribs 4
• floury potatoes 14 ounces (400g)
• light stock or water 6 1/2 cups (1.5 liters)
• parsley a small bunch, chopped
• blood sausage, boudin noir, or morcilla 9 ounces (250g)

1. Discard the toughest of the leaves from the leeks, then cut the tender white and palest green flesh into thin rounds.
2. Rinse thoroughly under running water to remove any trapped grit, then add them to a heavy saucepan with the butter.
3. Let them cook over low to medium heat for a good fifteen to twenty minutes, without letting them color, until they are soft enough to crush between your fingers.
4. Once they have started to soften, you can finely slice the celery and add it to the pan, then peel and chop the potatoes and stir them in too.
5. Cover the pot with a lid and let the vegetables sweat and soften without coloring, then pour in the stock or water and bring to a boil.
6. Decrease the heat so that the soup bubbles gently and partially cover it with a lid.
7. It will take about twenty-five minutes for the potatoes to become truly tender.
8. Blitz the soup in a blender or put it through a food mill, stir in the chopped parsley, and check the seasoning.
9. Cut the blood sausage into slices and grill until crisp.
10. Ladle the soup into bowls and float the sausage slices on top.
