Put all ingredients into a blender. Start on low speed and work up to higher speeds. Total blending at least 3 minutes.
Be careful to watch the consistency and add water if it looks too pasty after a long time blending.
This recipe is a riff based on multiple other recipes and a little experience and a little experimentation. Use the ingredients as a starting point. I find that the nuts behave differently at different times so you may need to add water or not.
