Step 1

Put the vegetable oil, tequila, lime juice, chipotle pepper, cumin, chili powder, garlic, oregano, salt, and pepper in a small food processor or blender and blend until smooth. Put the marinade in a plastic bag along with the chicken. Seal the bag and refrigerate for 6 to 8 hours.

Step 2

Preheat a grill or grill pan to medium-high heat. Add the jalapeno and grill until the skin is well charred. Remove the jalapeno to a small bowl and cover with plastic wrap to sweat the skin. When cool enough to handle, remove the stem, skin, and seeds, then finely mince.

Step 3

Heat a large, heavy bottom pot over medium-high heat and add 2 tablespoons of vegetable oil. Once hot, add the onion and saute until starting to caramelize, about 5 to 7 minutes. Add the garlic, minced jalapeno, chili powder, cumin, salt and pepper, to taste. Cook about 3 or 4 minutes, being careful not to burn the mixture. Deglaze the pan with some of the chicken stock, scraping up any brown bits from the bottom of the pan.

Step 4

Add the remaining chicken stock, the crushed tomatoes and the lime juice. Add the tortilla strips and bring the mixture to a boil, then lower the heat and simmer, uncovered, for 30 minutes. Taste and adjust seasoning.

Step 5

While soup base is simmering, heat a grill or grill pan to medium-high heat. Remove the chicken from the marinade and put on grill. Grill, turning until cooked through, about 14 to 18 minutes. Remove from the grill, to a large plate and when cool enough to handle, remove the skin and bones and shred. Keep warm.

Step 6

Heat the vegetable oil in a tall sided skillet to 350 degrees F. Add the tortilla strips and fry until they are golden brown. Remove to a paper towel lined plate and season with 1 teaspoon of salt and a pinch of chili powder.

Step 7

Combine the sour cream, 2 tablespoons tequila, and the remaining lime zest in a small bowl and season with salt and 1 teaspoon black pepper.

Step 8

To serve, put some of the shredded chicken in the bottom of each bowl and pour in the hot soup base. Top with diced avocado, fried tortilla strips, the tequila crema, and cilantro. Garnish with lime wedges and serve.
