To make St. Lucia Saffron Buns gluten-free, replace the all-purpose flour with a high-quality 1:1 gluten-free baking flour blend containing xanthan gum. Ensure that your yeast, baking powder, and cardamom (if used) are certified gluten-free. Because gluten-free doughs are typically softer, handle gently and allow a slightly longer rise time for the best texture. The resulting buns will still be tender, aromatic, and beautifully golden with the traditional saffron hue.
