Lightly broil the unseasoned chicken breasts until just cooked. Remove from oven and cut into large chunks.

Heat oil in a large non stick skillet over medium high heat. Add the cumin seeds, bay leaf, cloves, and cinnamon stick. Cook, stirring constantly for about 2 minutes. Add the garlic and ginger and cook 2 more minutes. Reduce heat to medium and add the onions. Cook for 15 to 20 minutes, stirring constantly.

Once onions are cooked and there is no trace of bitterness you should taste them, pour in the tomato pure and cook for 2 minutes. If the mixture seems too thick, add in the chicken broth. Sprinkle in the salt and sugar and cook 5 more minutes. Carefully sprinkle in the ground coriander and curry powder so that it does not clump, and mix well. Remove from heat.

Squeeze in the lime juice and mix in the cilantro. Stir in the strained yogurt and mix well. Remove all the large spices and leaves. Add in the chicken. Serve over basmati rice.
