CHICKEN BISCUITS

Steps:

• For biscuits:
• Preheat oven to 400°F. Place butter and shortening in freezer for 10 minutes.
• Blend 4 cups flour and next 5 ingredients in a food processor. Add butter and shortening. Pulse mixture until it resembles coarse meal, 20-25 pulses. Transfer mixture to a large bowl. Gradually add buttermilk while tossing mixture with a fork (mixture will not be completely incorporated). Knead in bowl with lightly floured hands just until dough forms, about 3 turns.
• Transfer dough to a lightly floured surface. Pat out dough until 1" thick. Lift 1 side and fold it over. Gently repeat 5 more times. Roll dough to 3/4"-thick round. Using a 3" biscuit cutter, cut biscuits from dough. Gather scraps and repeat patting out and cutting biscuits for a total of 10 biscuits.
• Place biscuits on a parchment paper- lined baking sheet, spaced 1"-2" apart. Bake until golden brown and a tester inserted horizontally comes out clean, 12-15 minutes. Transfer biscuits to a wire rack; let cool slightly. Serve warm or at room temperature. DO AHEAD: Can be made 8 hours ahead. Let cool completely. Store airtight at room temperature. Rewarm before serving.
• For fried chicken:
• Whisk buttermilk, dill, 1 1/2 teaspoons salt, 1 teaspoon pepper, and cayenne in a large bowl. Add chicken; turn to coat. Cover; chill at least 3 hours or overnight.
• Pour vegetable oil in a large pot to a depth of 2". Attach a deep-fry thermometer to side of pot. Heat oil over medium heat to 350°F.
• Whisk 1 1/4 cups water with remaining 2 teaspoons salt, remaining 3/4 teaspoon pepper, flour, and next 6 ingredients in a large bowl. Drain chicken well; pat dry with paper towels. Working in batches, dip chicken into batter. Fry chicken, turning occasionally, until skin is crispy and golden brown and chicken is just cooked through, 9-12 minutes per batch. Drain chicken on paper towels.
• Split biscuits in half; place 1 bottom half on each plate. Top each with a cheese slice, if desired, then a chicken thigh. Spoon Sausage Gravy over chicken, if desired. Place biscuit top over.
