Pollo Guisado con Chipotle y TequilaCasa Viejo is a very special place in the Polanco district of Mexico City. The restaurant is on the top floor of a small luxurious hotel with the same name. Traditional dishes, such as this braised chicken dish, are skillfully executed. Mexicans often add a bit of tequila to some of their dishes in the same way as wine or brandy might be used in other cultures. Tequila imparts a subtle peppery flavor to help balance and bring out natural flavors. Tequila also tends to mellow hot chiles. You can leave it out if you wish.
Heat 1½ tablespoons of the oil in a large ovenproof skillet over medium-high heat and cook the chicken until browned on both sides and firm to the touch, 4 to 5 minutes per side.
Season with salt.
Transfer the chicken to a plate.
To the skillet add the onion and garlic.
Cook, stirring, until softened, about 3 minutes.
Add the remaining ingredients, except the green onions.
Cook 5 minutes.
Return the chicken to the pan.
Bring to a boil, stirring to mix the chicken with the vegetables.
Transfer the pan to the oven and cook, uncovered, until the chicken and potatoes are tender, about 20 minutes.
Meanwhile, toss the green onions with the remaining oil and cook in a nonstick skillet over medium heat until starting to brown, but barely tender, 1 to 2 minutes.
Serve the chicken, potatoes, and sauce with green onions scattered on top.
