You don't need to soak the hemp hearts, but it will make the texture even better. Soak at least 15 minutes or overnight. Rinse well and place in blender with 4 cups of water. Boil 1 cup of water and pour over the pitted dates. Let sit 15 minutes, drain, add soft dates to blender with the coconut butter or cream. Blend on high for 1-2 minutes, until silky and smooth.
