To make these Indian Fry Bread Tacos gluten free, replace the flour with a certified gluten-free all-purpose flour blend that contains xanthan gum or a similar binder. Also verify that the baking powder and any taco fillings or toppings are certified gluten free if needed for strict dietary requirements. Because gluten-free dough can behave differently, you may need to adjust the milk or flour slightly to achieve a soft, workable dough. Handle the dough gently and expect a slightly more delicate texture when shaping and frying.
