Recently, I've been making my own nut milks instead of buying them for smoothies. They are surprisingly easy to make. I've only made cashew and hemp milk so far, as they don't require straining. This recipe is from Cookie and Kate!
1 cup cashews
4 cups water
2 tablespoons maple syrup (or honey)
1 pinch sea salt
1 tsp vanilla extract or 1 pinch cinnamon (optional)
Let cashews soak in a bowl of water overnight. Rinse and strain. Add cashews to blender with 2 cups water. Blend until smooth. Add the rest of the water, salt, sweetener, and other additions. Keep in refrigerator for a couple days.
