these are the best bottled barbecue sauces we've tried. Aside from the obvious -- the bone-in chicken -- the apple cider vinegar is perhaps the most important part of the Cornell chicken marinade.
Make the marinade: In a medium bowl, whisk together yogurt, garlic, vinegar, paprika, red pepper flakes and salt. Spatchcock the chicken: Place chicken, breast-side down, on a cutting board.
