A viscous food dispensing system comprising: a chute inlet configured to funnel whole food product into a sleeve; an auger configured to rotate within the sleeve, the auger having an over-center cutout; a processing surface extending downward from the chute inlet towards a curved base of the sleeve along a portion of the auger, the processing surface being spaced laterally apart from the auger to define a processing zone between the processing surface and the auger; a lock pin slidably received in the sleeve and movable between a locked position in which the lock pin engages the auger to restrict rotation of the auger, and an unlocked position in which the lock pin is disengaged from the auger, wherein the lock pin engages a pin receptacle formed in a radially-outward facing surface of the auger when in the locked position and engagement between the lock pin and the pin receptacle inhibits rotation of the auger in a first direction while allowing rotation of the auger in a second direction opposite the first direction; a stationary grinding plate having at least one set of grinding teeth and a movable grinding plate having at least one set of grinding teeth, the movable grinding plate selected for the at least one set of grinding teeth for a viscosity of a viscous food product, the movable grinding plate coupled to a proximal end of the auger so that the movable grinding plate rotates with the auger relative to the stationary grinding plate; an outlet adaptor that includes the stationary grinding plate and the movable grinding plate, and the at least one set of grinding teeth on the movable grinding plate move relative to the at least one set of grinding teeth on the stationary grinding plate to grind the particulate food product into a viscous food product while the movable grinding plate is rotating; wherein the whole food product is broken into particulate food product as the whole food product is captured between a leading edge of the over-center cutout and the processing surface while the auger is rotating, the auger configured to move the particulate food product away from the chute inlet to the movable grinding plate and the stationary grinding plate. a chute inlet configured to funnel whole food product into a sleeve; an auger configured to rotate within the sleeve, the auger having an over-center cutout; a processing surface extending downward from the chute inlet towards a curved base of the sleeve along a portion of the auger, the processing surface being spaced laterally apart from the auger to define a processing zone between the processing surface and the auger; a lock pin slidably received in the sleeve and movable between a locked position in which the lock pin engages the auger to restrict rotation of the auger, and an unlocked position in which the lock pin is disengaged from the auger, wherein the lock pin engages a pin receptacle formed in a radially-outward facing surface of the auger when in the locked position and engagement between the lock pin and the pin receptacle inhibits rotation of the auger in a first direction while allowing rotation of the auger in a second direction opposite the first direction; a stationary grinding plate having at least one set of grinding teeth and a movable grinding plate having at least one set of grinding teeth, the movable grinding plate selected for the at least one set of grinding teeth for a viscosity of a viscous food product, the movable grinding plate coupled to a proximal end of the auger so that the movable grinding plate rotates with the auger relative to the stationary grinding plate; an outlet adaptor that includes the stationary grinding plate and the movable grinding plate, and the at least one set of grinding teeth on the movable grinding plate move relative to the at least one set of grinding teeth on the stationary grinding plate to grind the particulate food product into a viscous food product while the movable grinding plate is rotating; wherein the whole food product is broken into particulate food product as the whole food product is captured between a leading edge of the over-center cutout and the processing surface while the auger is rotating, the auger configured to move the particulate food product away from the chute inlet to the movable grinding plate and the stationary grinding plate.
