To make Individual Yorkshire Puddings gluten free, replace the unbleached all-purpose flour with a high-quality 1:1 gluten-free all-purpose flour blend that contains xanthan gum or another binder. Confirm that the beef or bacon drippings are free from gluten cross-contamination. If using packaged bacon, check the label to ensure it is gluten free. Gluten-free Yorkshire puddings may be slightly more delicate and may not rise as dramatically, so keep the oven hot and avoid opening the oven door during baking.
