A method for food extrusion comprising the steps of: a) releasably installing an extrusion container having generally elliptically shaped open cavity with a frustro-conical shaped bottom terminated by a circular outlet on a base plate of an extrusion assembly; b) placing a food product to fill the cavity of the extrusion container, the food product including at least one soft constituent such as soft ice cream and the like; c) activating an elliptically frustro-conical shaped piston via a manual arm by applying pressure on the piston to downwardly push the food product contained in the cavity of the extrusion container, the piston being coaxial to the cavity and adapted to slidably engage the same; d) extruding the food product by providing circular downward flowing of the same with variable speed through the cavity down to the outlet of the extrusion container while performing a blending of air into the food product and twisting of the same; and e) collecting the food product being extruded from the container into a receiving receptacle with optimal stiffness, texture, density, feel and taste. Preferably, the food product includes at least two soft constituents placed adjacent to each other within the cavity.
