I see that Whole Foods has a recipe for making your own almond milk. No preservatives, sweeteners or extra ingredients. I am going to give it a try!
Makes 3 cups
Place 1 cup almonds in a bowl and cover by several inches with water. Cover and set aside at room temperature to soak overnight or 10-12 hours.
Drain and rinse almonds. In a high speed blender, blend almonds with 3 cups water until thoroughly combined. The mixture will be very frothy. Strain through cheese cloth, a fine strainer, or a nut milk bag. Store almond milk in the refrigerator and use within 3 days. Stir each time before using.
The leftover almond pulp can be dehydrated and used for baking.
