Emeril's Favorite Tortilla Soup

Why I Love This Recipe
I got this recipe from the "Emeril Live Show" on The Food Network. It is by far the best tortilla soup recipe that I have ever found. Making your own skinny tortilla strips from corn tortillas is the key to it tasting very authentic. I usually don't make the chipotle crema as my family is not a big fan of it with the soup.
Ingredients You'll Need
2 tablespoons olive oil
1 cup chopped onions
2 teaspoons chopped garlic
1 poblano pepper, seeded and chopped, or 1 pasilla or green bell pepper and 1 jalapeno pepper, seeded and chopped
1 1/2 teaspoons salt
1 1/2 teaspoons ground cumin
1/2 teaspoon ground coriander
1 tablespoon tomato paste
6 cups chicken stock
1 pound boneless, skinless chicken breasts, trimmed and cut into 1/2-inch cubes
1/4 cup chopped fresh cilantro leaves
2 teaspoons fresh lime juice
2 cups vegetable oil, for frying
6 stale corn tortillas, cut into 1/4-inch-thick strips
1 teaspoon Essence, recipe follows
1 avocado, peeled, seeded, and chopped, for garnish
Chipotle Crema:
1/2 cup sour cream
1 teaspoon chopped chipotle peppers in adobo sauce
1/8 teaspoon salt
In the bowl of a food processor or blender, combine all the ingredients. Process on high speed until smooth. Serve with the soup.
Directions
In a Dutch oven or large heavy pot, heat the oil on medium-high heat. Add the onions, garlic, peppers, salt, cumin, and coriander for 5 minutes. Add the tomato paste and cook, stirring, for 1 minute. Add the chicken stock and bring to a simmer. Simmer for 20 minutes. Add the chicken and simmer for 5 minutes. Add the cilantro and lime juice, and stir well. Remove from the heat and cover to keep warm.
Heat the oil in a heavy pot or electric fryer to 350 degrees F. Add the tortilla strips in batches and fry until golden and crisp, 1 1/2 to 2 minutes. Remove with a slotted spoon and drain on paper towels. Season with the Essence.
Ladle the soup into 4 or 6 serving bowls. Garnish each serving with the diced avocado, the fried tortilla strips, and Chipotle Crema.
