A head cabbage (white or red) is cut into quarters and sliced; kale is worked leaf by leaf. Raw, finely sliced cabbage makes a crunchy salad; cooked, it turns mild.
Heavy, dense, with tight leaves and no spots. Kale: firm, dark green leaves.
Remove the first damaged leaves. Cut the cabbage in four through the core, cut out the hard core at an angle on each quarter. For kale, hold the stem in one hand and slide the other along it to strip the leaf, the centre rib is too tough.
Three minutes for a cabbage, two for kale.
A whole cabbage keeps two to three weeks in the fridge. Cut, the cut side under film, a week. Kale, four to five days.
