Otto’s Naturals Cassava Flour is a great one-to-one replacement for all-purpose flour, especially by weight. If you sub in an equal weight of Otto’s, using a digital scale, most recipes will turn out great (FYI this method does not work with yeast-based recipes, though we have several fantastic ones already optimized for you on our recipes page).
If you don’t have a scale, just reduce volume by about 25%. For example, you can use ¾ cup of Otto’s per 1 cup of AP flour called for in your recipe.
As with all baking - weather, elevation, and brands of ingredients can all be HUGE factors in how your end product turns out. Pro tip: If your recipe ever turns out on the dry side, try reducing the flour instead of adding more liquid next time.
Happy Baking!
