Chop the cabbage
Grate the carrots, and add to the cabbage with all mentioned supplies. Sugar is optional - it just gives a better crunch to the cabbage, but it will be also good without sugar.
mix everything with your hands, you also can squash the mix a bit
it should look like this
Put the cabbage mix in a bigger bowl, put a plate over it and put something heavy on the plate. Leave it like that for 3 days, room temperature.
Optional: each day take the press off, thrust in a knife or a spoon handle in the cabbage mix to let the air in
After 3 days the cabbage should be crunchy and also a bit acidic. Put it in a jar and keep it in the fridge.
This goes well with vodka :-)
