Because when making Coke chicken wings, the Coke was poured in. It was originally black, but when the soup was boiling, it turned white. It was because he had a reaction with the iron pot this time. He will make Coke next time. When making chicken wings, put less ketchup and add Coke after cooking. The color will look better and the taste will be better. You should put more Coke in the chicken wings and no MSG.
