I got the base for this soup from the movie Tortilla Soup, but I've tweaked it to my own personal taste. This soup makes a great start to any Cinco de Mayo celebration, or a good warm up on a chilly Fall night. Hope you enjoy it and let me know what you think.
Whisk together the heavy cream and buttermilk. Let stand in a warm place for 8 hours to make Crema
Place the garlic and tomatoes in a blender and beat until smooth
Heat the olive oil over low heat. Add the chicken and saute just until it looses the outside pink color; add the onions, salt and pepper and cook, stirring frequently, until onions are a pale brown and caramelized, about 10 minutes.
Stir in the tomato puree and cook another 10 minutes, stirring often
Pour in the chicken stock, and add in the chipotle chili, bring to a boil then reduce heat to a simmer and cook uncovered for 20 minutes. Stir in the tortilla strips and cook 10 minutes longer, until the strips are softened. Remove and discard the chili.
Serve with Crisp fried tortilla strips, cilantro, avocado chucks, lime wedges, and the cream and buttermilk mixture (Crema).
Sometimes I like to add a little kick to the soup so I'll add diced jalapeno or ghost peppers, but be careful as the ghost pepper really packs a punch.
