Combine all flour blend ingredients in a large container that has a tightly sealing lid. Replace the lid and shake the contents vigorously several times, in all directions.
Remove the lid and use a whisk to finish combining the ingredients.
To make larger amounts, simply move the servings slider to the right until you reach your desired amount (I always make 2.8kg (20 cups)).
Flour blend can be stored in a cool, dark area (such as a pantry or closet) up to three months. For longer storage, freeze for up to one year.
