The Core of King Arthur Flour: Unbleached American Wheat
At its most fundamental, flour is a simple ingredient, but the quality of the wheat and the milling process make all the difference. King Arthur’s flours are renowned for their purity and consistency, which starts with their foundational ingredient: high-quality American wheat. The specific type of wheat varies by the flour, but it's often hard red wheat, known for its high protein content.
What truly sets King Arthur apart is its commitment to using only naturally aged, unbleached flour. While many competitors use chemical treatments like bleach to whiten and soften flour instantly, King Arthur allows its flour to oxidize slowly and naturally over several weeks. This process not only avoids chemical additives but also develops the flour's gluten-forming potential, leading to more elastic doughs and superior results. This promise of “never bleached, never bromated” is a hallmark of the brand's quality.
The Importance of Protein and Enzymes
Protein content is a critical factor for bakers, as it determines the amount of gluten a flour can form. More gluten means a stronger, stretchier dough, ideal for lofty yeasted breads, while less gluten creates tender, delicate baked goods like cakes. King Arthur maintains strict specifications for the protein content in each of its flour types, a consistency that many other brands lack.
In some of its refined flours, such as all-purpose and bread flour, King Arthur adds a small amount of an enzyme, often from malted barley flour. This enzyme aids in the fermentation process, helps produce a better rise, and enhances the browning of the final product. This attention to detail demonstrates their focus on providing optimal baking performance.
Ingredient Breakdown by Flour Type
King Arthur offers a wide range of flours, each with a slightly different composition to suit specific baking needs. Here is a look at the ingredients for some of their most popular products:
- Unbleached All-Purpose Flour: This includes unbleached hard red wheat flour and a touch of enzyme, such as malted barley flour. It is milled to a versatile 11.7% protein content.
- Unbleached Bread Flour: Made with unbleached hard red wheat flour and an enzyme. It has a higher protein content of 12.7%, specifically designed for yeast breads and pizza dough.
- Organic All-Purpose Flour: This flour is milled from 100% organic hard red winter and spring wheats. Unlike the conventional version, it is unenriched.
- Self-Rising Flour: This is a blend of unbleached soft wheat flour, leavening (baking soda, sodium acid pyrophosphate, monocalcium phosphate), and salt. It is lower in protein to create tender baked goods.
- 100% Whole Wheat Flour: This product is simply 100% hard red whole wheat flour, containing the bran, germ, and endosperm for a robust, nutrient-rich profile.
