Celery root, or celeriac, is an under-appreciated vegetable that always pleases. I love it shredded, in a creamy salad called celery remoulade, but I think cooking brings out the best in this vegetable. It develops some sweetness, as does the red cabbage, which also contributes texture to this comforting colcannon. The purée will take on a pinkish hue from the cabbage.
