A lid and blade assembly for a micro puree machine includes a lid having a central aperture for receiving a central hub of the blade. At least two cutting arms and at least two mixing arms extend radially outward from the central hub. A retaining component retains the blade within the lid during processing. The lid includes a recess below the retaining component for collecting slush and ice displaced by the blade during processing. Portions of the blade also include serrated grooves for clearing slush deposits when the blade engages the lid.
