Combine red chile peppers, cumin seeds, coriander seeds, cinnamon stick, ginger, garlic, peppercorns, and cloves in a mortar and pestle or a food processor; grind or process into a paste (masala paste).
Heat oil in a large pot. Add onion and until golden brown. Stir in masala paste and cook for 2 minutes. Add pieces of chicken; mix well and pour in enough cold water to cover the chicken. Bring to a boil.
Cover and simmer until chicken is cooked through, about 30 minutes. Season to taste with tamarind juice and salt. Stir well and cook for additional 5 minutes. Garnish with fresh cilantro.
