A kitchenware apparatus and container for producing fermented vegetables, such as sauerkraut, comprising a screw top or Mason jar, a threaded jar lid with moat and an oblong top slot opening, an inverted cup that fits within the moat, a plunger sized to fit within the neck of the jar and having a keyed handle that extends up through the slot in the lid, and a compression spring. The lid moat and inverted cup comprise an airlock or one way valve that allows fermentation gases to escape but prevents outside air from entering. The screw lid, spring and plunger comprise a press that compresses the fermenting vegetables to press juice from the vegetables and to hold the vegetables under the liquid surface to prevent mold or other spoilage and to prevent browning.

1. A device for fermenting vegetable foods, comprising: a jar having an open top with a neck,a cap fitted to the neck of the jar so as to be attachable to the jar neck in sealed relationship, and with an airlock to allow escape of gases from the jar when the cap is in place but not to allow entry of
1. A device for fermenting vegetable foods, comprising: a jar having an open top with a neck,a cap fitted to the neck of the jar so as to be attachable to the jar neck in sealed relationship, and with an airlock to allow escape of gases from the jar when the cap is in place but not to allow entry of air into the jar,a plunger below the cap, including a horizontal plunger base plate, configured to substantially span across the jar internally so as to be capable of pressing down and holding down a mass of vegetable foods within the jar, anda compression spring between the cap and the plunger base plate, the compression spring being configured and positioned to engage against a bottom of the cap and to press down on the plunger so that the plunger base plate is pressed downwardly when the cap is secured on the jar and a mass of vegetable foods is contained in the jar. 2. The device of claim 1, wherein the plunger includes a plunger handle extending upwardly from the plunger base plate, the compression spring being a coil spring encircling the plunger handle when the cap is on the jar, and the upper end of the handle formed into a key to fit through a slot in the center of the cap so that the plunger handle can be pushed up through the slot of the cap against the force of the spring to compress the spring, then turned so that the key crosses the slot and retains the compression spring compressed between the plunger base plate and the cap. 3. The device of claim 2, wherein the airlock comprises an annular moat formed in the top of the cap to retain water, and an inverted cup to rest in water contained in the moat. 4. The device of claim 3, wherein the key comprises a pair of key arms extending laterally from the plunger handle, and the slot in the cap is of a length sufficient for the plunger handle with arms to pass through. 5. The device of claim 1, wherein the airlock comprises an annular moat formed in the top of the cap to retain water, and an inverted cup to rest in water contained in the moat. 6. The device of claim 1, wherein the cap is internally threaded, the jar having a complementarily threaded neck, so that the cap is attached by screwing the cap down onto the jar neck. 7. The device of claim 6, wherein the cap comprises two components, a main component of diameter to extend across the open top of the jar and having an annular rim of diameter to engage down against the top of the jar neck, and a separate threaded ring to engage the threads of the jar neck and to press down against the rim to firmly engage the rim against the jar neck when the threaded ring is fully threaded down onto the jar. 8. A device for fermenting vegetable foods, comprising: a jar having an open top with a neck,a lid fitted to the neck of the jar so as to be attachable to the jar neck in sealed relationship, and with an airlock to allow escape of gases from the jar when the lid is in place but not to allow entry of air into the jar,a mechanical press below the lid including a base positioned to press down on a mass of vegetable material contained in the jar when the lid is secured on the jar. 9. The device of claim 8, wherein the jar is of transparent glass. 10. The device of claim 8, wherein the mechanical press includes a compression coil spring which acts between the lid and the base to push the base downwardly, pressing a mass of vegetable material when contained in the jar. 11. The device of claim 8, wherein the lid comprises two components, a main component of diameter to extend across the open top of the jar and having an annular rim of diameter to engage down against the top of the jar neck, and a separate threaded ring to engage the threads of the jar neck, and to press down against to firmly engage the rim against the jar neck when the threaded ring is fully threaded down onto the jar.
