this is probably the simplest Puerto Rican rice recipe, and that is saying a lot for an island that has more ways to cook rice than square feet of land.
Heat the oil in a large pot over medium heat. Add rice and cook for a couple of minutes stirring occasionally.
Pour in the chicken stock, sazón, and salt. You want enough chicken stock to cover all of the rice by 1 inch. Cover and bring to a boil, then reduce heat to low and cook, covered, for another 20 minutes. If the rice is undercooked once all the stock is absorbed, add in a little water, cover, and continue to cook on low until rice achieves desired consistency.
