Puree the sauerkraut in a blender until it is completely smooth, roughly three minutes. Sprinkle the Methocel into the pureed sauerkraut and shear for thirty seconds. When the Methocel is fully dispersed, pass the mixture through a fine mess strainer. Cool the base to ten degrees C. Spray acetate sheets with pan release and wipe them clean to leave a fine non-stick film. Spread the sauerkraut in a fine layer over the acetate sheets. Place the acetate sheets in a dehydrator and dry until the sauerkraut is removed easily from the acetate and is dry and lightly crispy.
