How to Make It
Cook rice according to package directions.
Heat oil in a pressure cooker over medium-high; if using an electric cooker, add oil, and set to sauté. Add onion, and cook, stirring occasionally, until tender and just starting to brown, 3 to 4 minutes. Add garlic and ginger; cook, stirring occasionally, until fragrant, about 1 minute. Stir in garam masala, salt, coriander, turmeric, cumin, black pepper, and cayenne pepper. Cook, stirring often, until fragrant, about 1 minute. Stir in chicken, tomatoes, and broth. Secure the pressure cooker lid, and cook until chicken is cooked through, about 8 minutes.
Release pressure valve of the pressure cooker, and remove lid. Whisk together cream and cornstarch; add to sauce, and stir to combine. Cook until slightly thickened, about 1 minute. Serve chicken tikka masala over rice; sprinkle evenly with cilantro.
