Buy some good quality organic bone-in chicken thighs and ask the butcher at the meat counter to remove the bone for you. They are happy to do this and make sure to save the bones in your freezer to make stock and bone broth. Let the chicken thighs come to room temperature for 20 minutes and then season with a generous pinch of salt and pepper on both sides. Pre-heat a cast iron or non-stick pan over medium heat for 2 minutes with 1 tablespoon of oil. Add the chicken skin side down and cook for 7-8 minutes or until the skin is deep golden brown. Flip and cook another 3-4 minutes until the chicken is cooked through. Remove the chicken from the pan, pour off all fat, and cover chicken loosely with foil. Add the chicken stock to the pan along with the lemon juice, capers, and bring to a simmer. Cook for 10 minutes or until the liquid has reduced by half. Add the butter along with the parsley, lower heat to low, and cook another 1-2 minutes until the sauce has thickened up a bit. Turn the heat off the pan and set aside.
