Beetroot & red cabbage sauerkraut

Tip all the ingredients into a large bowl, add 1-1½ tsp freshly ground black pepper, then scrunch it all together with your hands for 5 mins. You might want to wear gloves to avoid staining your skin with the beetroot juices.

Press the veg down in the bowl with your hands, then cover the surface and up the side of the bowl with a large sheet of compostable cling film or something reusable like a beeswax wrap. Now place another similar-sized bowl on top. Press down hard and add anything heavy (packs of rice or cans work well) to weigh it down so the juices rise to cover the surface. Cover again.
