1Cut chicken into 1 inch cubes. In a large skillet saute chicken in oil and butter till golden. Remove from skillet and set aside. In the same skillet saute onion until soft. Add Fresh garlic and ginger and stir. Add carrots and stir. Add curry, garam masala, cinnamon and cumin. Stir to coat. Add flour, stir and cook for 30 seconds. Add stock and stir until thickened. Return chicken to pan and simmer until carrots are tender, about 20 minutes. Add peas stir until hot. Season with salt and pepper. Serve over your favorite rice. Basmati Rice is great for this dish.
If you don't have or can't find garam masala, just double the curry powder. It is still excellent but I think the garam masala adds depth to the dish.
