Black Bean Soup

Langkah-langkah

1. Heat the olive oil over medium heat in a large soup pan. Add the onions, garlic cloves and carrots and cook, stirring occasionally, until onions are soft and translucent, about 8 minutes. Do not brown.
2. Add the black beans, chicken broth, cornmeal, oregano, coriander, cumin, cayenne pepper and salt and bring to a boil. Reduce the heat, cover and simmer gently for about 15 minutes.
3. Purée the soup using a hand-held immersion blender until very smooth and creamy. (Alternatively, you can use a standard blender to puree the soup in batches; see note.) Stir in the lime juice and season with salt and pepper to taste. Ladle the soup into bowls and top each bowl with a dollop of sour cream and freshly chopped cilantro.
