In a large bowl, thoroughly mix the shredded cabbage with pickling salt, juniper berries, and caraway seeds.
Use your hands or tongs for the best result.
Pack the seasoned cabbage into a large plastic food container or a pickling crock.
Make sure to press it down tightly to remove any air pockets.
Combine water with additional pickling salt, then pour into a zip-top bag.
Seal the bag tightly and place it on top of the cabbage mixture to weigh it down.
Leave the mixture at room temperature to ferment.
This process should take about two weeks, depending on your room temperature.
Check the sauerkraut daily.
Taste your sauerkraut after about 10 days and let it ferment longer if you want a stronger flavor.
Refrigerate once it's to your liking to stop the fermentation process.
