Clean all equipment thoroughly.
Remove any wilted or discolored outer leaves from the cabbage.
Cut the cabbage into quarters, remove the core, and thinly slice the cabbage.
Place the sliced cabbage in the large mixing bowl
Sprinkle the salt over the cabbage and massage it with clean hands for about 5 minutes until the cabbage becomes soft and releases its liquid.
Add the Caraway seeds and the peppercorns.
Pack the cabbage and its liquid tightly into the quart-sized mason jar, leaving about 1 inch of headspace at the top.
Place the weight on top of the cabbage to keep it submerged under the liquid.
Cover the jar with cheesecloth or a clean kitchen towel and secure it with a rubber band.
Let the jar sit at room temperature (60-75°F) for around 2 weeks. Check the sauerkraut daily, pressing down on the weight to keep the cabbage submerged. Skim off any scum that may form on the surface.
Taste the sauerkraut after 1 week and continue fermenting until it reaches your desired level of tanginess.
Once the sauerkraut is ready, remove the weight and cheesecloth, seal the jar with a lid, and store it in the refrigerator. The sauerkraut will keep for several months.
