Prep Tips – To get the most accurate measurements, use a kitchen scale or if you are using measuring cups, spoon the flour into the measuring cup and then level it. Don’t scoop the measuring cup into the flour.

Baking Tips – When adding this flour to recipes, use a scale to measure the flours and spoon the flour into the measuring cup, then level it.

Difference Between All Purpose and 1:1 Flour Blends –  Xanthan gum is added to 1:1 flour blends to provide structure and elasticity that gluten free baked goods lack. It also helps baked goods hold their shape after baked. A little xanthan gum goes a long way.
