Almond flour is a versatile and nutritious ingredient that has gained popularity in recent years as a gluten-free alternative to wheat flour. To make blanched almond flour, the almonds are first soaked in hot water to loosen their skins, which are then removed by hand or using a machine. The blanched almonds are then dried and ground into a fine powder using a food processor or a high-powered blender. Unblanched almond flour (also referred to as almond meal) retains the almond skin and has a darker color.
