Bread Flour vs. All-Purpose Flour: What’s the Difference and Are They Interchangeable?

With the increase of baking at home over the past year, there are times when all-purpose flour or bread flour is in high demand. So what do you do if you want to make a loaf of homemade bread but don't have any bread flour (or the store is out)?

Prepping, proofing, and baking. The process of making bread from scratch can be a long one, but is one of the most satisfying ways to pass the time (in my opinion, at least). In the past year, Americans seem to agree with me, as 80% of home bakers enjoyed the chewy, delicious results of freshly-baked bread due to spending more time at home. With baking therapy becoming a part of people's normal routines, there's a chance you've wondered if you can substitute bread flour for all-purpose flour (and vice versa). So if you run out or there's no bread flour left at the store, read on to learn the difference between the two types of flour. Then you'll know exactly what will happen if you substitute one for the other in your baking.

Bread Flour vs. All-Purpose Flour

Both flours are made from wheat and literally sit next to each other in the baking aisle of the grocery store. So what's the difference between all-purpose flour and bread flour, anyway? The short answer: protein and gluten content. According to the pros at Bob's Red Mill, bread flour has approximately 13% more protein than all-purpose flour. This produces a higher amount of gluten, allowing for a higher rise and the chewy, light texture you expect from a loaf of bread. And as the name implies, all-purpose flour is really for all types of baking purposes (i.e. cakes, cookies, and quick breads). The lower protein amount, however, allows for the same firm texture and structure of bread, but with less rise.
