The chicken and potatoes in this Cuban stew become fall-apart tender from simmering in a tomato sauce studded with salty, briny green olives. Some versions of this dish call for marinating the chicken in the juice of naranja agria or sour oranges before cooking. In my take, I add orange and lime juices right into the sauce to cut back on time and to flavor the tomato broth.
Heat the olive oil in a medium heavy bottomed pot or Dutch oven over medium-high heat. Season the chicken on both sides with 2 teaspoons salt and a few cracks of pepper. Add the chicken skin-side down and cook in two batches until golden brown and crispy and the skin releases easily from the skillet, 5 to 8 minutes. Flip the chicken over and cook 3 minutes. Remove to a plate, leaving the fat in the pot.
Add the onion, bell pepper, 1 teaspoon salt and a few cracks of pepper and cook, stirring occasionally and scraping the bottom of the pot with a wooden, until the onions soften, about 5 minutes. Stir in the garlic and Sazón seasoning and cook until fragrant, about 30 seconds. Add the vino seco and scrape up any browned bits with the wooden spoon to deglaze the pot.
Stir in the tomato sauce, lime and orange juices, olives, potatoes and bay leaf. Nestle the chicken in the liquid and bring to a boil, 1 to 2 minutes. Cover the pan and simmer over low heat until the chicken is almost covered with the liquid, 15 minutes. Stir, pushing the chicken further into the liquid and simmer another 15 minutes. Remove the lid and cook uncovered until the liquid has reduced slightly and the potatoes are fork tender, 20 to 25 minutes. Discard the bay leaf and serve over white rice if desired.
Vino seco is a golden cooking wine often used in Cuban cooking. It's available online or at markets that specialize in Cuban groceries.
