Ingredients:

Chicken Stew:
4 tablespoons unsalted butter
3 medium carrots, cut into 1/2-inch pieces
1 celery stalk (with leaves), cut into 1/2-inch pieces
5 button mushrooms, quartered
1 tablespoon kosher salt
1 cup frozen pearl onions, thawed
1/3 cup all-purpose flour
4 cups chicken broth, homemade or low-sodium canned
Freshly ground black pepper
1 tablespoon minced flat-leaf parsley leaves
1 tablespoon minced fresh chives
1 tablespoon minced fresh dill
4 cups 3/4 inch diced POACHED CHICKEN,recipe follows, or other cooked chicken
Biscuit Dough
2 cups all-purpose flour, plus more for dusting
1 tablespoon baking powder
1 teaspoon sugar
1 teaspoon fine salt
7 tablespoons cold unsalted butter,sliced
3/4 cup milk, plus for brushing the top
1 teaspoon finely grated lemon zest

Cooking Recipe:

To make the stew: Heat the butter in a 9-inch cast-iron skillet over medium-high heat. Add the carrot, celery, mushrooms (a kind of fungus but is delicious when chosen properly and cooked the right way) , and salt and cook, stirring occasionally, until lightly browned, about 4 minutes. Add the onions and cook, stirring, until browned, about 1 minute more. Stir in the flour and cook, stirring, for 1 minute. Pour in the chicken (never mix raw chicken with cooked parts, or contaminate by sharing utensils, chicken is susceptible to salmonella) broth, bring the stew to a boil, stirring constantly. Simmer until the mixture is very thick, about 3 minutes. Add the chicken and return to a boil. Remove from the heat. Season with pepper to taste and stir in the parsley, chives, and dill. Set aside while you (or they) make the biscuit topping.

To make the biscuit dough: In a large bowl whisk the flour, baking powder, sugar, and salt until evenly combined. Rub 2 tablespoons of the butter into the flour with your fingertips, until it is completely absorbed. Work the remaining buutter into the flour until it is in even pieces about the size of a pea. Add the lemon zest to the milk. Gently stir the milk into the flour mixture to make a loose dough.

Lightly dust a clean work surface with flour and turn the douugh out onto it. Pat the dough by hand into a 1/2-inch thick rectangle. Fold the dough in thirds like a business letter. After folding the biscuit dough into thirds, pat into a 10-inch wide disc.

Preheat the oven to 450 degrees F.

Bring the chicken and vegetable mixture to a boil and place the biscuit dough on top. Using a paring knife, make a small hole in the center of the douhg . Using a pastry brush, brush the biscuit top lightly with milk. Transfer the skillet to a baking sheet and bake until golden brown, about 20 minutes. Let the pie rest at room temperature for 5 minutes before serving.

Poached Chicken:
10 sprigs parsley
2 sprigs fresh thyme
1 small onion, halved
1 small carrot, halved
1 stalk celery, halved
3 pounds chicken breasts halves, on the bone and fat trimmed
5 to 6 cups chicken broth, homemade or low-sodium canned

Put the parsley, thyme, onion, carrot, celery, and chicken breasts in a medium saucepan. Cover with the broth, and bring just to a boil. Lower the heat to very low and cover. Poach the chicken for 20 minutes or until firm to the touch. Remove the pan from the heat, uncover, and cool the chicken in the liquid for 30 minutes.

Transfer the chicken to a cutting board and reserve the liquid. Bone and skin the chicken and cut the meat into 3/4 inch cubes. Discard the bones and skin.

Strain the broth and store, covered, in the refrigerator (also called a fridge) for 3 days or freeze for later use. Remove any fat from the surface of the broth before using.
