Homemade Plant-Based Milk

Combine oats, almonds, and cashews in a large bowl and cover with 2 cups filtered water. Allow to soak in the refrigerator for at least 8 hours.

Remove from the refrigerator and add flax seeds. Let stand so flax seeds react with the water and mixture comes to room temperature, about 1 hour.

Transfer to a blender and blend until creamy. Let rest for 5 minutes. Add remaining 2 cups filtered water. Blend until well combined, smooth, and creamy. Strain the pulp through a fine-mesh sieve. Enjoy right away or refrigerate for up to 1 week. Shake well before use.
