Recipe by Grace Parisi from the foodandwine.com

MASALA MARINADE
. 1 cup plain low-fat yogurt
. 2 garlic cloves, minced
. 1 tablespoon finely grated fresh ginger
. 1 1/2 teaspoons ground cumin
. 1 1/2 teaspoons ground coriander
. 1/4 teaspoon ground cardamom
. 1/4 teaspoon cayenne pepper
. 1/4 teaspoon ground turmeric
. Salt and freshly ground pepper
CHICKEN
. 2 1/2 pounds skinless, boneless chicken thighs, fat trimmed
. Salt and freshly ground pepper
. 2 tablespoons plus 1 teaspoon vegetable oil
. 1/4 cup blanched whole almonds
. 1 large onion, finely chopped
. 2 garlic cloves, minced
. 1 teaspoon minced fresh ginger
. 1 1/2 tablespoons garam masala
. 1 1/2 teaspoons pure chile powder
. 1/2 teaspoon cayenne pepper
. One 35-ounce can peeled tomatoes, finely chopped, juices reserved
. Pinch of sugar
. 1 cup heavy cream
DIRECTIONS
. MAKE THE MASALA MARINADE: In a large glass or stainless steel bowl, combine the yogurt, garlic, ginger, cumin, coriander, cardamom, cayenne and turmeric. Season with salt and pepper. 
. PREPARE THE CHICKEN: Using a sharp knife, make a few shallow slashes in each piece of chicken. Add the chicken to the marinade, turn to coat and refrigerate overnight. 
. Preheat the broiler and position a rack about 8 inches from the heat. Remove the chicken from the marinade; scrape off as much of the marinade as possible. Season the chicken with salt and pepper and spread the pieces on a baking sheet. Broil the chicken, turning once or twice, until just cooked through and browned in spots, about 12 minutes. Transfer to a cutting board and cut it into 2-inch pieces. 
. Meanwhile, in a small skillet, heat 1 teaspoon of the oil. Add the almonds and cook over moderate heat, stirring constantly, until golden, about 5 minutes. Transfer the almonds to a plate and let cool completely. In a food processor, pulse the almonds until finely ground. 
. In a large enameled cast-iron casserole, heat the remaining 2 tablespoons of oil until shimmering. Add the onion, garlic and ginger and cook over moderate heat, stirring occasionally, until tender and golden, about 8 minutes. Add the garam masala, chile powder and cayenne and cook, stirring, for 1 minute. Add the tomatoes with their juices and the sugar and season with salt and pepper. Cover partially and cook over moderate heat, stirring occasionally, until the sauce is slightly thickened, about 20 minutes. Add the cream and ground almonds and cook over low heat, stirring occasionally, until thickened, about 10 minutes longer. Stir in the chicken; simmer gently for 10 minutes, stirring frequently, and serve. 
. Variation The marinade and sauce here are also delicious with shrimp, lamb and vegetables.

MAKE AHEAD
. The Chicken Tikka Masala can be refrigerated for up to 3 days. Reheat gently before serving.

SERVE WITH
. Steamed basmati rice, rice pilaf or warm nan.

My Changes to the Recipe

The directions say to broil the chicken. I chopped the chicken up to marinate it and then I just cooked it in a separate pan for about 10 minutes and then added it into the tagine, don't add all of the juice.

When sauteing the onions, garlic, and ginger I added mushrooms, pablano and serrano peppers. I only did a half of the serrano, because I had some people over that hadn't tried Indian food before, so I didn't want to add too much of a kick.

I added cilantro in at the end and also some tomato paste, because it was really creamy. I added a dash of nutmeg, cardamon, red pepper flakes, and cumin.

Instead of nan, we used the fresh tortillas that you cook yourself and they were a pretty good substitute!
