A blade assembly for a micro puree machine including a central support hub, a cutting blade, a mixing blade, a central opening, an angled ledge and an undercut. The cutting blade extends outward from a circumferential surface of the central support hub and defines a curved leading edge. The central opening is configured to receive a power shaft therein. The angled ledge is located at an upper end of the central support hub and extends about at least a portion of an outer perimeter of the central support hub. The undercut is located on the outer perimeter of the central support hub and is positioned closer to a lower end of the central support hub than the angled ledge. The undercut includes an engagement surface that extends outwards from a central axis of the central support hub and is configured to receive and retain a clip mechanism.
