Don't belong. Special flour does not belong to high gluten flour. Teyi flour is medium gluten flour, which is usually sold in supermarkets in the form of high-grade "jiaozi noodles" packaged independently, and is mainly used to make jiaozi and some fine noodles. The high-gluten flour has high protein content and strong gluten, and is often used to make bread and noodles, which is elastic and chewy. In western-style cakes, it is mostly used for muffins (thousand-layer cakes) and cream hollow cakes (puffs). In cakes, it is only used for high-content fruit cakes.
