Pack cabbage mixture down into a large plastic food container. Top with a lid smaller than the opening of the container and place a glass jar filled with the quart of water on top of the lid. Place in cool area overnight (65 to 70 degrees F). In a day, the cabbage should have given up enough liquid to be completely submerged. The jar serves as a weight to keep the cabbage submerged and away from air.
Check cabbage every other day for approximately 2 weeks and skim the surface of scum, if necessary. Let stand for 4 weeks. Transfer to an airtight container and store in the refrigerator for up to 6 months.
