In a mixing bowl, combine chicken, ginger-garlic paste, turmeric, chili powder, lemon juice, and salt. Let it rest for at least 30 minutes or longer if you have time. The spices will soak in, the meat softens, and the flavor deepens.
Heat a grill or grill pan and sear the marinated chicken until lightly charred on both sides. You’re not cooking it through yet, just giving it that smoky edge that defines Kuku Paka.
In a large pot, heat oil or ghee. Add chopped onions and sauté until golden. Stir in ginger-garlic paste and cook until fragrant. Add turmeric, cumin, and coriander powder the aroma should bloom instantly.
Pour in the grated or blended tomatoes and cook until the oil begins to separate that’s when the magic starts.
Add the grilled chicken to the pot and pour in coconut milk. Stir gently, letting the sauce coat the chicken completely. Drop in the green chili.
Cover and let it simmer on low heat for 15–20 minutes. The sauce thickens, the flavors merge, and the chicken turns tender.
