Extruded Novelties

Products with no sticks, like bars with fancy shapes, or with sticks but irregular sides, such that they could not be pulled out of a mold, are frozen by extrusion. In such a process, the shape is formed and sliced, either vertically or horizontally as below, that slice is further hardenend by passing it through a cold tunnel, and then nuts or syrup can be coated on it, it can be enrobed with chocolate sauce, or whatever is desired to give the final product. Horizontal extrusion is used to make the "chocolate bar analogue" type of products, while vertical extrusion is used to make everythng from chocolate-enrobed ice cream slices to fancy-shaped novelties on a stick.
