To start Sauerkraut For each 2 large heads of cabbage. (I prefer to use a mixture of Savoy and red cabbage.) You need: 1½ Tablespoons (about 25ml) of vinegar. I like to use live vinegar from a vinegar mother 4 teaspoons raw sugar 1 tablespoon of best quality sea salt Wash and shred the cabbage and pack tightly in jars or a plastic container with a tight fitting lid. Divide the other ingredients between the containers. Cover the cabbage with boiled water and cover tightly. Place in a cool place to mature, it takes about three weeks or so, and will stay fresh and crisp for years, as long as it is kept below about 15 Celcius.. The liquid left in the container becomes a “Sauerkraut Mother”. It can, and should be used to seed future batches of Kraut, in place of the boiled water above. The flavour of each should improve over the last as the bacillus mature and “good” bacteria displace the less good ones. The very best will give you cabbage that will be extraordinarily crisp and tasty, and remain so for as long as you need. Apart from that, a tablespoon or so of mature sauerkraut mother liquid taken at least once per week is a very good way to keep the flora in the gut working properly. You should particularly always dose yourself if you ever have to take a course of antibiotics.
