Notes
* For better flavor and color, use 4 bone-in chicken thighs with skin and another 12 to 16 ounces of boneless skinless chicken thighs or breast meat.** For better flavor and color, add 2 fresh red chilies when blending the shallots, garlic, and ginger. Alternatively, you can add in 1 teaspoon of chili powder when mixing in the dry spices. You can do both if you like a spicy curry.
