  • ½ small red cabbage
  • ½ small white cabbage
  • 2 garlic cloves
  • 2 carrots
  • Knob of ginger
  • Knob of turmeric root
  • ¼ packet of Caldwell’s vegetable starter or whey
  • 1 tablespoon Himalayan salt or Celtic salt
  • 1 tablespoon Fennel seeds to aid digestion
  • Filtered water.


  • Grate all ingredients (except starter) and mix together in a large bowl. Mash with potato masher or squeeze with your hands to start to get the juices out of the vegetables.
  • Mix starter culture with 1 cup of room temperature water and salt and sit for 10 minutes. Add to vegetables
  • Start adding vegetables to a large glass jar (around 2 litres) pushing down with a masher or rolling pin to get rid of air bubbles and get more juice out.
  • Leave space at the top (about 3 cm) so that it does not overflow while fermenting. Make sure all the vegetables are covered with water/brine then weigh them down with fermenting weights or a cabbage leaf. Lacto-fermentation is an anaerobic process and oxygen will ruin the process. Therefore ensure the lid on tight. Ideally, use a pickle pipe.
