If you’re looking for the secret to tender fried chicken, marinate the chicken in spiced buttermilk before you fry it. Lightly season buttermilk and soak the chicken pieces in the marinade for several hours. Then toss the pieces in a spice mixture and let the chicken rest to absorb even more flavor. Heat oil and fry the chicken until it’s crispy and golden brown. Eat buttermilk fried chicken while it’s hot or enjoy cold leftovers the next day.
