To make the cashew cream, click on the picture in this blog post for additional details. Alternately, you could soak cashews in warm water using a 2:1 ratio. For example, I typically make cashew cream in larger batches, so I will soak approximately 4 cups raw cashews in warm water (enough to cover all cashews) and use 2 cups of that water to blend with the 4 cups cashews. 2 measurements of cashews : 1 measurement of water.
