Remove the outer leaves from the cabbage and discard all but one.
Chop the cabbage into thin strips and place in a bowl. Add the caraway seeds.
Sprinkle the salt on top and let it rest for five minutes. Use your judgement on the salt. Start slowly with 1 tbsp and see how it tastes. You want it to taste salty but not over salty. If that makes sense haha.
Now, massage the cabbage and salt together. You will quickly start to see the liquid that you will use as your brine.
Fill clean mason jars or you can use a crock. Save about 1-1/2 inch head space at the top.
Pour that brine liquid over the cabbage. Make sure it covers it. If it didn't make quite enough, that's ok. You can just add some extra water.
Next, take that outer cabbage leaf that you saved and place it on top.
If you have a weight, put that on top of the cabbage leaf, making sure none of the sauerkraut is exposed.
Put your lid on and sit on the counter for 7-14 days, depending on how warm your house is.
Store in the refrigerator, up to a year.
