I have been making my own, raw almond milk because I don’t like that there are sweeteners in the store bought kind. The only thing I had to buy for extra “equipment” was a milk bag (mine is actually a produce bag that has fine enough holes to use as a milk bag). You could also just use a cheesecloth, I bet.
I soak 1 cup of almonds in water for 12-24 hours. When I want to make the milk, I rinse the almonds and put half in the blender with 3 cups of water. Blend. Place the milk bag into a pitcher and pour the blended almonds and milk through the bag. Then you can strain it into the pitcher just like you are “milking” the bag. I repeat the process once more and I have homemade, and raw almond milk for drinking, using in lattes, or pouring over my cereal.
