Soak the almonds for at least 4-6 hours, preferably overnight.
Drain and rinse the almonds. You can peel them, but that's not necessary.
Add the almonds, water, and dates to a blender and blend until smooth. Add more or less water depending on how thick you want your almond milk to be. I usually add 3 to 4 cups of water (750 ml to 1 l).
Strain the mixture using a nut milk bag, a cheesecloth, a napkin, or a strainer.
