Sweet Potato Soup
Soups are so comforting in the winter months and are easy to make with seasonal root vegetables like sweet potatoes.
1. In large pot, heat oil over medium heat. Add garlic, onion and chili powder, and sauté for about 5 minutes or until onions are soft. Add the broth and sweet potatoes, and bring to a boil. Reduce heat and simmer until potatoes are soft, about 20 minutes.
2. Transfer the pot's contents to blender or food processor, in batches, or use an immersion blender in the pot. Purée until very smooth, adding some of the milk if necessary to thin. Return soup to pot, if necessary.
3. Return soup to pot (if you haven't already), and stir in milk. Heat over medium heat, stirring, until steaming, but do not let boil.
4. In a small bowl, whisk cornstarch into 1/2 cup (125 mL) of the yogurt. Stir into soup and heat, and then stir for 1 minute. Season to taste with pepper. Stir lime zest and juice into remaining yogurt. Ladle soup into warmed bowls, and dollop lime yogurt on top of each serving.
