Coq au Vin

Heat 1 tablespoon of the oil in a large (5-qt) Dutch oven or heavy-bottomed pot over medium heat. Add the pancetta and cook until the fat has rendered and the pancetta is crispy, 5 to 8 minutes. Using a slotted spoon, transfer the pancetta to a paper-towel-lined plate, leaving the fat in the pan.

Return the pot to the stove and reduce the heat to medium-low. Add the onions to the pot and cook, stirring occasionally, until the onions are softened and just starting to brown, 3 to 5 minutes. Add the garlic and cook, stirring constantly, until fragrant, about 1 minute more. Add the Cognac and cook, stirring to scrape the brown bits from the bottom of the pan, until the Cognac has evaporated. Add the wine, chicken broth, tomato paste, balsamic vinegar, sugar, thyme, bay leaf, and ½ teaspoon salt. Bring to a boil, then reduce the heat to medium and gently boil, uncovered, for 15 minutes.

While the chicken cooks, heat the remaining 2 tablespoons of oil in a large skillet over medium heat. Add the mushrooms and ¼ teaspoon salt and cook, stirring frequently, until the mushrooms are golden brown, about 5 minutes. Set aside.

Increase the heat in the Dutch oven/pot to medium and stir in three-quarters of the flour and butter paste. Gently boil until the sauce is thickened, 5 to 7 minutes; add the remaining paste if you'd like the sauce a little thicker. Fish out and discard the bay leaf.
