Mix all the spices well, then marinate with ribs. Increase / decrease the spice to fit the amount of ribs so don't be too salty. Marinated overnight so the next day just grilled, or marinated the ribs in the refrigerator for 2 hours for the ribs to be spiced and then grilled. Preheat the Air Fryer for 5 minutes before baking at 320 degrees for 25-30 minutes. Very fast, isn't it?
