In a small bowl combine garlic, ginger, turmeric, salt and 1 tablespoon of vegetable oil. Mix together and rub all over chicken thighs. Set aside to marinate for 30 minutes and make the mango sauce.
In a blender add the mango, Sriracha sauce and lemon juice. Purée to smooth and set aside.
Preheat over to 350°F. In an oven proof skillet (I use my cast iron) add the remaining tablespoon of vegetable oil and over medium high heat brown the chicken on both sides. Season with salt and brush with a quarter of the mango sauce.
Bake for 35 to 40 minutes until golden brown and chicken is cooked through. If it gets too brown before it’s done, cover with aluminum foil and return to the oven. Baste with mango sauce once before removing from oven to caramelize on top. Serve with remaining mango sauce, chopped cilantro on top and side dish of choice.
