In a bowl, wash the rice until the water runs clear. Transfer to a rice cooker pot that's at least a 10 cup cooker. In a separate bowl; combine the rest of ingredients. Making sure to combine the seasonings until dissolved and the achiote powder is well mixed. Taste a bit and adjust the salt and seasonings according to your taste preference.
Pour over the rice in the cooker and stir well to combine. Press button to cook; halfway through cooking time, stir to combine the ingredients thoroughly. Let cooking time finish. Let sit a few minutes before enjoying.
This can also be cooked on the stovetop. Bring the rice to a full boil, stir, cover with a lid and lower heat to about med-low. Continue cooking for about 20-30 minutes. Make sure to keep an eye on it as not to burn. That's why I prefer the rice cooker.
