In a bowl, combine garlic, sugar and the Peri-Peri sauce.
Season chicken with salt. Place chicken in a large resealable bag. Add the marinade and close. Rub the bag to coat the chicken then refrigerate overnight.
Remove chicken from marinade and transfer to a roasting pan.
Rub chicken skin with oil. Add 2 tablespoons of the marinade back to the pan.
Baked for 45 minutes at 200c, skin side up. I switch the oven to fan mode (or broil mode) after 20 minutes to make the skin crispier.
Baste chicken with drippings from the pan every 15minutes or so. This is optional but if you have the time, please do it!
Serve while warm with your favorite carbs and salad. Enjoy!
