In a high speed blender or food processor, add your blanched almonds and blend very well, until a superfine powder remains. Shake the flour and blend once more, to ensure it is completely blended.
Transfer your flour into a sealable container or jar.
Notes
TO STORE: Just like any other flours or baking staples, blanched almond flour can be stored at room temperature, in a sealed container. They will keep well for 6 months. Any longer and the flour will begin to clump up and become thick. TO FREEZE: Place the flour in a ziplock bag and store it in the freezer for up to 6 months.
