Marinate: In a mixing bowl, combine the chicken pieces with Kay's Masala and lemon juice. Ensure every piece is well-coated. Let the chicken marinate for 20 minutes.
Onions: In a wide pan, heat the oil over medium heat. Add the diced onions, frying them until they turn translucent.
Chicken: Introduce the marinated chicken to the pan. Let it cook for 10 minutes, stirring occasionally to ensure even cooking.
Simmer: Pour in the 0.5 cup of water, then cover the pan with a lid. Allow the chicken to simmer for another 10 minutes.
Serve: Dish out the deliciously prepared Chicken Curry onto a plate. It pairs wonderfully with naan, bread, or rice. Enjoy your meal!
