When preparing gluten-free appetizers, it's crucial to ensure that all ingredients are verified to be gluten-free, as cross-contamination can occur if utensils or surfaces have previously been in contact with gluten-containing foods. Opting for naturally gluten-free ingredients and checking labels for gluten-free certification can help ensure a safe and enjoyable appetizer experience for everyone, including those with gluten intolerance or celiac disease.
