The red cabbage (Brassica oleracea var. capitata f. rubra) is a kind of cabbage, also known as purple cabbage, red kraut, or blue kraut after preparation.
Red cabbage lends itself beautifully shredded in salads and coleslaws or fermented in sauerkrauts. But this vegetable can be eaten cooked too but it does tend to turn blue with heat. To avoid this you can add a little vinegar or lemon to your pot..
