Sweet Potato, Chipotle, and Apple Soup

Sweet potatoes and apples are a common fall combination, though not one I've ever had in a soup. This soup is sweet and mild, with a little kick from the chipotle peppers and makes a nice light dinner when accompanied by a side salad and some crusty bread. Although I've included it below, I skipped the fried corn tortilla garnish in favor of a nice side salad and leftover Beaten Biscuit that I had in the freezer (which, for the record, held up quite well in the freezer).

Sweet Potato, Chipotle, and Apple Soup
from Food and Wine
serves 6

2 tablespoons vegetable oil, plus 1 cup for frying
1/2 medium white onion, finely chopped
2 garlic cloves, smashed
1 teaspoon finely grated fresh ginger
2 Gala apples—peeled, seeded and coarsely chopped
1 celery rib, thinly sliced crosswise
1 3/4 pounds sweet potatoes, peeled and thinly sliced
1 quart chicken stock or low-sodium broth
3 cups water
1 small canned chipotle in adobo sauce, seeded and minced
Salt and freshly ground white pepper
1/2 teaspoon cinnamon
1/2 teaspoon sugar
3 yellow corn tortillas, cut into 1/2-inch strips

1. In a medium soup pot, heat 2 tablespoons of the oil until shimmering. Add the onion, garlic and ginger and cook over low heat, stirring, until softened, about 7 minutes. Add the apples and celery and cook for 5 minutes. Add the sweet potatoes and cook for 5 minutes. Add the chicken stock and water and bring to a boil. Cover partially and simmer over low heat until the fruit and vegetables are very tender, about 45 minutes. Stir in the chipotle.

2. Working in batches, puree the soup in a blender until smooth. Season with salt and white pepper and return to the pot.

3. In a small bowl, mix the cinnamon and sugar with 1/2 teaspoon of salt. Heat the remaining 1 cup of oil in a medium skillet. Add the tortilla strips and fry over high heat, stirring, until crisp and golden, about 2 minutes. Drain on paper towels and sprinkle with the cinnamon-sugar mixture. Serve the soup in shallow bowls and garnish with the fried tortilla strips.
