Step 3
Add the remaining 2 tablespoons butter to the pressure cooker and stir in the carrots, celery, onion, turnip, and garlic cloves. Cook until softened, about 10 minutes. Then stir in the flour and cook until the mixture starts to turn golden, about another 3 minutes. Stir in the chicken stock, scraping up the browned bits from the bottom of the pot, and nestle the browned chicken into the vegetables. Cover and cook on high pressure for 13 minutes, and then release the pressure manually. Transfer the chicken pieces to a plate, reserving the broth in the pot. When the chicken is cool enough to handle, remove the bones and skin if you like, and tear the meat into chunks.
