This is something I have been drinking in my coffee and I have really enjoyed it. Cashew Milk with 1 or 2 dates in a high speed blender a few times a week as a treat. The rest of the time it's just coffee and cashew milk.
Cashew milk is really easy to make. You do however need to have a high speed blender (Blendtec, Vitamix). Soak 1 cup raw cashews overnight in water. In the morning strain out the old water and place the soaked cashews in the blender. Add 3 cups of water and blend until smooth. There is no need to strain the mixture like almond milk. I make almond milk the same way but you have to use a nut milk bag or cheesecloth to strain out the pulp. Cashew milk is easier since you don't have to do this.
Cashew milk is also great in cooking for whole 30 as well as a dairy substitute.
