What is Almond Flour?

It’s made with the starchy parts of wheat grain, so its nutrient value loses in the equation. You generally cannot substitute almond for all-purpose in a recipe. The shelf-life and expiration date comparison gives white flour higher scores.
  • Coconut is a nut flour higher in carbs but lower in fat than almond.
