Ingredients

  • 3 tablespoons olive oil
  • 6 cups thinly sliced leeks, white and light green parts only
  • 8 cups 1/2-inch diced, peeled sweet potatoes, stored in water
  • 3 cups 1/-inch diced, peeled yams, stored in water
  • 1/2 teaspoon sea salt
  • 12 twists freshly ground pepper
  • 2 sprigs fresh thyme or 1/2 teaspoon dried thyme leaves
  • 2 bay leaves
  • 8 cups water or vegetable stock
  • salt and freshly ground pepper to taste
  • thinly sliced scallions and fresh cilantro leave for garnish

Method

  • 1. Heat the oil in a large soup pot over medium heat. Stir in the sliced leeks. Drain the diced sweet potatoes and yams and add them to the pot.
  • 2. Sprinkle with 1/2 teaspoon of salt and a dozen twists of freshly ground pepper. Stir in the thyme and bay leaves. Cook for 10 minutes, stirring occasionally.
  • 3. Stir in the stock or water. Bring the soup to a boil. If using bouillon paste, add it now. Lower the heat so the soup simmers, partially covered, for 20 minutes. The sweet potatoes and yams will be quite tender.
  • 4. Use a blender to puree one-fourth of the soup until very smooth and creamy. Return the puree to the pot. Adjust the salt to taste.
  • 5. Just before serving, swirl in the fresh spinach until wilted,
  • 6. Serve Sweet Potato Leek Soup with Fresh Spinach garnished with thinly sliced scallions and leaves of fresh cilantro.
