If you're wondering why your fry bread isn't coming out fluffy, there are a few possible reasons. First, make sure you're using the right type of flour. A light, all-purpose flour will produce a lighter, fluffier fry bread than a heavier whole wheat flour. Second, don't overwork the dough. Knead it just enough to form a ball, then let it rest for a few minutes before shaping it into a flat disc.
Third, make sure your oil is hot enough before you add the dough. If it's not hot enough, the bread will absorb too much oil and become greasy. Fourth, don't overcrowd the pan. Fry the bread in batches so each one has plenty of room to expand.
And finally, don't be afraid to experiment. Try adding a little baking powder to the flour for extra lift, or using a different type of oil. With a little trial and error, you'll soon find the perfect formula for fluffy, delicious fry bread.
