Yes, baking powder can be a great way to add some flavor and texture to your chicken wings. If you are looking for a crunchy outside, adding a little baking powder to the marinade can do the trick. Depending on how much you want to add, it will either lightly coat the wings or give them an extra crispy finish. However, make sure not to add too much baking powder as it can leave a bitter aftertaste in the wings. Additionally, be sure to check your marinade for any other ingredients that may contain carbs before you decide to use baking powder. Enjoy!
