Youguozi, a traditional Chinese snack, can be classified into two main types: large Youguozi and small Youguozi, which each have distinct salty or sweet flavors. Skilled cooks use a variety of techniques including flipping, turning, squeezing, pressing, kneading, twisting, pinching, and picking to shape the dough into various artistic designs. These doughs are then deep-fried in sesame oil to achieve the desired crispiness and golden color, resulting in the delicious final product known as Youguozi.
