Gluten-free bread is made without wheat, barley, or rye, which contain gluten. Instead, it's made from alternative flours such as rice, corn, or potato flour. To make gluten-free bread, the flour is mixed with other ingredients like yeast, eggs, and water, then kneaded and baked. Some gluten-free bread also includes xanthan gum or guar gum to help bind the ingredients and create a more traditional texture.
