To cook tandoori chicken in a Whirlpool 20C 118 microwave oven, you should use the "Convection Mode" if available. Tandoori chicken is traditionally cooked in a tandoor, which is a clay oven that uses dry heat. The convection mode in a microwave oven is designed to replicate the dry heat cooking environment, making it the most suitable option for tandoori-style dishes.
The convection mode in a microwave oven uses a fan to circulate hot air, providing even heating and browning. This helps achieve a similar effect to traditional tandoor cooking, giving your tandoori chicken a crispy and flavorful exterior while keeping the inside tender and juicy.
If your microwave has a specific preset for tandoori chicken, you can use that as well, as it will set the appropriate cooking parameters for the dish. However, if there is no tandoori chicken preset, the convection mode is the best option for cooking this dish.
Keep in mind that cooking times and temperatures may vary based on the recipe and the size of the chicken pieces, so it's always a good idea to follow a reliable tandoori chicken recipe and adjust the cooking time as needed.
