Youtazi is a traditional Jiuquan snack. To make it, start by pouring boiling water into flour, then add a small amount of yeast and cooking oil. Knead the mixture vigorously and let it rise. Next, roll the dough into thin pancakes and brush them with oil. Sprinkle sesame seeds on top and roll them into sausage shapes. Cut them into equal pieces and twist each piece into a spiral shape. Steam the Youtazi until they turn a deep yellow color and become soft and flaky. When you bite into them, the oil seeps out, giving the snack a fragrant and delicious flavor.
