To make this Firecracker Chicken Recipe gluten free, verify that the cornstarch, hot pepper sauce, rice vinegar, honey, crushed red pepper flakes, and sesame seeds are labeled gluten free. Use gluten-free hot sauce, as some brands may contain gluten-based additives or cross-contact warnings. White rice is naturally gluten free, but confirm the package if needed. Use clean cookware, utensils, and serving dishes to prevent cross-contact with gluten-containing foods.
