Stir the rinsed rice into the thick sauce until the grains are evenly coated.
Add the chicken stock, bring to a gentle simmer, then cover the pot tightly.
Cook over low heat for 25 to 30 minutes, until the rice is tender and the liquid is absorbed.
If the rice is still firm, add a small splash of stock or water, cover, and steam for a few more minutes.
Turn off the heat and let the rice rest, covered, for 10 minutes.
Fluff gently, discard the bay leaves, and serve with chicken, plantains, and parsley or scallions.
