I make the kale chip coating in the Thermomix, as the high speed of the machine breaks down the lemon very well. You could blitz the mixture in a blender or food processor instead. You can soak the cashews if you wish to help them blend with the rest of the ingredients. I don't bother and still get quite a creamy mixture. I make these in a dehydrator, but I have provided oven dried instructions as well. I have not made them this way but many others have success with making kale chips in this manner.
