All-purpose flour is not a blend of which types of wheat?

All-purpose flour is a versatile flour that is commonly made from a blend of hard and soft wheat. This allows it to have a moderate gluten content, making it suitable for a variety of baked goods, from breads to cookies. The combination of hard wheat provides strength and structure, while the soft wheat adds tenderness.

On the other hand, soft and medium wheat typically refers to flours that are lower in protein and are often used for products like cakes and pastries that require a lighter texture. Therefore, it does not contribute to all-purpose flour, which benefits from the balance offered by both hard and soft wheat.

Durum wheat is specifically used for making pasta and has a very high protein content, which is quite different in purpose and application compared to all-purpose flour. Additionally, whole wheat flour is milled from the entire wheat kernel and contains more fiber, which further distinguishes it from the blended nature of all-purpose flour.

Lastly, while hard red and soft white wheat are both incorporated into different types of flour, the answer highlights that all-purpose flour does not incorporate soft and medium wheat in its formulation, establishing why this choice correctly responds to the question regarding the components of all-purpose flour.
