To make homemade almond milk: Soak 1 cup raw almonds in a bowl with 2 cups water, 8 hours to overnight. Transfer almonds and water to a blender and blend until it reaches a pasty consistency. Pour mixture through a cheesecloth-lined strainer into a bowl, squeezing excess liquid out of the almond meal. The remaining almond meal can be used in baking after it has been dried out a bit.
If making homemade almond milk, total time increases to about 10 hours to allow almonds to soak completely, so start the night before.
