First of all, we'd better prepare high-gluten flour when preparing flour, because the effect made of high-gluten flour will be crisp.
You should put a little more baking powder in the flour, so that the volume of the flour can become larger, and the made proper fruit will be crispy.
Then, when kneading the dough, you must knead it several times repeatedly, so as to knead out the small bubbles in the dough and make the proper fruit crispy and delicious.
When baking proper fruit, be sure to coat the prepared food with a layer of cooking oil, which will make proper fruit taste more delicious.
