Remove outer leaves from cabbage, core, and shred thin; rinse cabbage with cold water and drain.
Place drained cabbage in a large mixing bowl and toss with the salt.
Muddle with a wooden meat tenderizer or mallet to release as much liquid as possible.
Pack cabbage tightly into a clean fermentation jar leaving 2-1/2 inches of headspace.
You should have enough liquid from the muddling to cover the cabbage. If not, top up with some extra brine (2 tablespoons pickling salt to one quart distilled water).
Place ceramic weights or a plate on top of the cabbage to keep it totally submerged.
Clean the rim of the jar from any cabbage bits sticking to it.
Top the jar with the lid and insert the air lock and bung. Fill the air lock halfway with water to seal the airlock from air.
Ferment:
Place the fermenter at room temperature between 70F-75F. Do not stir contents during fermentation. Skim off any yeast that occurs. There should not be any mold, but if it occurs, skim it out.
At 70-75F, fermentation should complete in 3-4 weeks. At 60-65F it can take up to six weeks. At temps below 60F, fermentation may not occur. At temps above 75F cabbage will become very soft (not desired).
During fermentation you will see air bubbles coming up and escaping through the airlock. This is expected, desired and fine. When the bubbles stop, fermentation is complete.
At this point, you can either refrigerate or water bath can the kraut. Fridge kraut will be more crisp.
Yield: Approximately one-half gallon.
Canning Tips
To water bath can kraut, bring the kraut and brine to a full boil.
Pack hot kraut into sterile canning jars leaving half inch headspace. Tap out bubbles and top with brine if needed.
Secure with sterile lids and bands.
Process times:
0-1000 feet: 10 min. for pints, 15 min, for quarts
1001-6000 feet: 15 min/pints, 20 min/quarts
above 6000 feet: 20 min./pints, 25 min./quarts
Refrigerating any jars that the lids do not seal properly.
