An egg food product and a method for making the same. In one embodiment the method of making a food product comprises feeding a liquid composition into a cavity, the liquid composition comprising at least 80% liquid egg comprising albumen and yolk; mixing the liquid composition in the cavity; raising the temperature of the mixed liquid composition to above 175° F.; and after raising the temperature, extruding the mixed liquid composition through a die cavity having a temperature greater than 175° F. to solidify and shape the mixed liquid composition into a solid composition; and cutting the solid composition to a desired length.

A kit for molding and storing malleable foodstuff includes (a) a molding tube; (b) a plunger slidable within the molding tube for tamping foodstuff received therein to form a shaped food article corresponding in shape to an interior of the molding tube; and (c) at least one storage tube sized and shaped for storing the shaped food article therein with reduced surface area contact relative to the molding tube.
