Sauerkraut is so easy to make at home and fun to experiment with. It might take a few batches to discover how it works best for you. It is important that you use organic vegetables so that no chemicals can interfere in the fermentation process. The same goes for salt, use pure sea salt free from anti-caking agents or iodine. I use Malden flakes.
1 medium organic cabbage, try pointed, white, savoy or red (about 500g)
4 tsp sea salt
You will also need:
1 large Kilner jar – sterilized in the dishwasher or very hot water.
1 smaller jam jar (or drinking glass) that fits inside the neck of the bigger jar, sterilized as above
A large ceramic or glass mixing bowl
Core and slice the cabbage into a bowl, add the salt and squeeze the cabbage with your hands. You should see a reduction in volume after a few minutes as the salt encourages the liquid out of the cabbage and it begins to wilt.
Keep going until you have plenty of liquid then pack the cabbage and its liquid into the jar, pushing it right down until the liquid rises up over the cabbage. I use the base of a smaller jar or glass to push it down. It is important that the cabbage remain under the liquid level while it ferments so top up with a little water if it’s not wet enough but the volume will reduce as it ferments, so it becomes easier.
Fill the small jar with water and leave on top as a weight to keep the cabbage underwater, leave the Kilner jar open but cover with a piece of muslin and leave to stand at room temperature somewhere it won’t be disturbed.
After a day you should see bubbles rising up, check the cabbage is submerged and push down again. Depending on your kitchen, the season and where you live, getting to the right stage of fermentation could take a couple of weeks, if it is very cold, longer. After a week, taste a little every few days and when it is tangy enough for your liking, close the lid and store in the fridge.
