Soak 1 cup raw almonds in bowl with plenty of room temperature water for 6-8 hours. (Soaking will make the almonds softer and more digestible.)
Drain the almonds in a colander and rinse with fresh water.
Place the almonds in a blender or Vitamix. Add 3 cups fresh water and blend until the nuts are pulverized.
Strain through a fine mesh sieve, cheesecloth or a nut milk bag into a glass bowl. If using a sieve, use a spoon to scrape the almond meal around and allow as much liquid to drain through.
Transfer to a glass jar and refrigerate, covered for up to 4 days. Add the remaining pulp, sweetened with honey or maple syrup, to hot cereal, granola or fruit.
