Add the garlic and stir for 30 seconds.
Add the rice and stir for 1 minute.
Turn the Instant Pot off.
Add all the remaining ingredients - cumin, chili powder, cayenne pepper, salt, tomatoes, tomato sauce and broth or water. Stir to mix well.
Put the lid on the pressure cooker and on the Rice setting for 8 minutes or use Manual mode for 8 minutes if your Instant Pot doesn't have a rice setting.
