To make this recipe gluten free, replace the self-rising or all-purpose flour with a certified gluten-free all-purpose flour blend that is suitable for frying. Also confirm that the cornstarch, garlic salt, paprika, cayenne pepper, and any seasoning blends are labeled gluten free, as ingredients and manufacturing practices may vary by brand. If using a gluten-free flour blend without leavening, the coating may be slightly different in texture but will still fry well. Always use clean oil and utensils to avoid cross-contact.
