Ingredients
2 cups lentils
2 to 4 tablespoons butter
1 onion, finely diced
1 bay leaf
6 cups vegetable or chicken stock (or water)
Sea salt and freshly ground black pepper
2 large garlic cloves
2/3 cup lightly toasted walnuts
½ cup plus 2 tablespoons crème fraîche
2 tablespoons minced parsley, optional.
Preparation
Soak the lentils in water for 2 hours, then drain.
Melt the butter in a large pot over low heat. Add the onion and bay leaf. Sauté over medium-high heat until onion is translucent, 5 minutes. Add lentils, stock and 1 teaspoon salt. Bring to a boil, then reduce heat. Simmer, covered, until lentils are soft, about 30 minutes. Season with salt and pepper.
Using a mortar and pestle, pound the garlic with a large pinch of salt. Add the walnuts and work until finely ground. Add 2 tablespoons crème fraîche, mixing it in a teaspoon at a time, to form a paste.
Add the remaining ½ cup crème fraîche to the finished soup. To serve, ladle the soup into bowls and top each with a large spoonful of walnut cream, a bit of ground pepper and, if desired, a sprinkle of parsley. Serves 4 to 6. Adapted from “Vegetable Soups,” by Deborah Madison.
