The Core Ingredients of King Arthur Bread Flour
King Arthur's commitment to quality baking starts with the purity of its ingredients. The standard unbleached bread flour is a testament to this philosophy, containing only a handful of components sourced and milled in the United States. The ingredients are intentionally simple, focusing on the quality of the raw materials rather than relying on additives. The primary component is hard red wheat flour, which is naturally aged rather than chemically bleached. The high protein content of this wheat is what gives bread flour its strength, allowing it to develop a robust gluten structure necessary for creating voluminous, chewy yeasted breads. The secret to its reliable performance, however, lies in its secondary ingredient: malted barley flour or an enzyme.
The Role of Malted Barley Flour
The addition of malted barley flour is a crucial element that distinguishes premium bread flour. This is not simply a filler but a functional ingredient that significantly improves baking performance. Malted barley flour contains active enzymes, specifically alpha-amylase, which help break down the complex starches in the flour into simpler sugars. These sugars then become a food source for the yeast during fermentation, leading to several key benefits:
- Enhanced Rise and Volume: By providing the yeast with a more accessible food source, the malted barley flour boosts fermentation, resulting in a more vigorous rise and greater oven spring.
- Improved Crumb and Texture: The presence of these enzymes helps condition the dough, contributing to a softer, more tender crumb and a moister finished product.
- Better Crust Color: The increased sugar content available for fermentation also contributes to better browning of the crust during baking, creating a richer, more golden color.
It is this synergistic combination of high-protein hard red wheat and enzymatically active malt that gives King Arthur bread flour its consistent, dependable results.
A Simple Formulation for Superior Quality
What is also important to note about King Arthur bread flour is what is not included. The company is committed to producing flour that is never bleached, never bromated, and never enriched or fortified with additional nutrients. This approach stands in contrast to many other national flour brands that use chemical treatments or fortification. King Arthur instead allows its flour to age naturally, which both whitens and conditions the flour slowly over a period of weeks. This means that the flour's excellent performance comes from the intrinsic quality of the wheat and the natural enzyme activity, not from artificial manipulation. King Arthur is also non-GMO certified, which provides an additional layer of transparency and reassurance to consumers.
A Baker's Checklist for Using King Arthur Bread Flour
- Higher Protein Content: Its 12.7% protein content is higher than many other national brands, meaning it can absorb more liquid. Adjust your recipe accordingly by adding a couple of extra teaspoons of water per cup of flour to achieve the proper dough consistency.
- Perfect for High-Rise Breads: Use it for all your yeasted baked goods, including artisan loaves, pizza crust, rolls, and more.
- Boost Whole-Grain Bakes: Combine it with whole wheat flour to add extra lift and structure to denser whole-grain recipes.
- Natural and Pure: Trust that you are using a flour free of chemical bleaches, bromates, and artificial preservatives.
- Reliable Performance: The company's rigorous testing ensures a consistent and dependable product every time you bake.
