Preheat the oven to slow 150°C
(300°F/ Gas 2). Quarter the cabbage and remove the
core. Finely slice, then place in a
large casserole dish with the onion and apple. Toss together well. Combine the garlic, cloves,
nutmeg, soft brown sugar and vinegar in a small bowl. Pour the mixture over the cabbage,
and toss. Dot the top with the butter, then
cover and bake for 90 minutes, stirring once or twice. Season to taste, with salt and
freshly ground black pepper, and serve hot.
