- Make sure everything is clean! You only want good bacteria when you are making sauerkraut.
Remove any wilted outer leaves of the cabbage and wash it if it’s not organic.
Cut the cabbage into quarters, remove the core and slice into thin strips (about ½ cm wide).
Put cabbage into the bowl and sprinkle the salt over.
Using clean hands, massage the salt into the cabbage leaves for 5-10 minutes until you start to get juice releasing from the cabbage.
Sprinkle caraway seeds (if desired) over cabbage and mix through.
Place handfuls of cabbage into the mason jar and really press it down to make sure there isn’t any air bubbles left.
Continue until your jar is full to about 5cm / 2in from the top.
Pour any remaining juice in to completely cover the cabbage. NOTE: if you find you don’t have enough juice, just add a little bit of salty water – about 1 teaspoon of salt per cup of water will do. Just make sure you use distilled water as tap water will kill the good bacteria you are trying to attract!
Weigh the cabbage down so it stays under the liquid – use one of the outside leaves of the cabbage cut to fit inside your jar and then use something to hold it down. There are a few ways you can do this – use a smaller jar that will fit inside your mason jar filled with water or you can also use a clean stone (called a pickling stone). If you can’t find either of those then you can use a piece of the cabbage core to wedge in and hold everything under the brine.
If your jar has a lid, place it on but don’t completely tighten it. If you don’t have a lid, use a piece of cheesecloth over the top of the jar and fasten it with a rubber band.
Now find a cool, dark place for your sauerkraut to live while it ferments. It’s a good idea to place a small plate or saucer under the jar just in case any liquid escapes.
In the first couple of days you will need to check every day to make sure everything has stayed under the brine (and press it down if it hasn’t).
Fermentation will take between 3 and 10 days, depending on your local weather. Try tasting it after 3 days and when it tastes good to you, remove the weight and if you used cheesecloth place the sauerkraut into a glass container with a lid.
Place your sauerkraut into the fridge and it is ready to enjoy. It can keep refrigerated for at least 2 months but it tastes so good I’m sure it will not last that long!
