I cook this whenever I do my Christmas Ham with Prunes and Red Cabbage recipes. The three work wonderfully together. Its taken from Scandinavian Holiday Recipes. I have copied the recipe directly but I've never added the herbs or leeks (I always seem to forget) and I must warn you that every time I do this the potatoes take ages (an hour or so!) to cook, maybe its me doing something wrong. The saving grace is that if you do do it to accompany the ham and cabbage, both of those recipes are very forgiving timewise ; ie the ham can be turned down and then rested and the red cabbage can simmer away quite happily just being stirred occasionally.
