All-purpose flour is a versatile type of wheat flour that is milled from hard red wheat or a blend of hard and soft wheats, typically at an 80:20 ratio. It is suitable for all types of baked goods, such as bread, biscuits, pizza, cookies, muffins, and can also be used to thicken gravies and sauces. All-purpose flour is a medium-strength, medium-gluten flour thats designed to be suitable for baking everything from crusty breads to delicate pastries and cakes. It is a blend of strong and weak flours formulated to be acceptable for making crusty breads as well as delicate pastries and cakes. All-purpose flour has a moderate amount of protein, around 10 to 12 percent, which is lower than bread flour but higher than cake flour. It is available bleached, which creates a softer texture, as well as unbleached, which provides more structure in baked goods and retains more of the nuance of the wheat. All-purpose flour can be used for various purposes, but for the best results, it is always recommended to use the flour that is recommended in the recipe, such as cake flour for cakes and strong bread flour for bread.
