Place all the ingredients into a large bowl and massage with your hands for 10 minutes or so to release the juices.
Pack the vegetables firmly into a 1 litre wide mouth glass jar, leaving about 4cm room at the top of the jar to allow for expansion. If necessary, add filtered water to cover the carrots.
Use a weight such as a river stone to keep the carrots submerged in the liquid. Alternatively, use a jar with an air-lock.
Cover the jar with a double layer of cloth and seal with a rubber band. Or, place the lid loosely back on the jar. Leave at room temperature in a low-light area for 3 – 10 days and then transfer to the fridge.
