1 - step 1 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.

2 - You might want to wear gloves to avoid staining your skin with the beetroot juices.

3 - step 2 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.

4 - Now place another similar-sized bowl on top.

5 - 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.
