Heat the annatto / achiote oil in a pan.
Add the garlic and onion and cook gently until slightly softened.
Add the carrot cubes and peas.
Add the rice. Stir to coat each grain of rice with the oil. Cook for a few minutes.
Transfer the rice mixture to the rice cooker. Pour in the broth. Taste; add salt and pepper, as needed.
Turn on the rice cooker and cook the rice, as usual.
When the rice is done, leave for a few minutes in the cooker then fluff up the grains using a fork.
Serve the rice hot. It is great by itself or with anything and everything — meat, vegetables, seafood.
