Similar to bubble and squeak, Rumbledethumps is a traditional Scottish dish of buttery mash, cabbage and rutabaga (swede), baked until golden brown and crispy.
You can cook it earlier in the day and reheat in the oven – give them an extra 20 minutes or so from cold.

Recipe by Sue Lawrence for BBC Good Food

Serves 6

1 1/2 lb large potatoes, peeled and chopped into large chunks
14 oz rutagaba (swede) peeled and chopped into large chunks
3-4 oz unsalted butter
9 oz savoy cabbage or kale, finely sliced
salt and freshly ground black pepper
3-4 oz mature cheddar, grated

Set the oven to 350F.

Cook the potatoes and swede in a saucepan of salted boiling water until tender. Drain well and return to the pan.

Heat 50g/2oz butter in a pan and gently cook the cabbage for a few minutes, until the cabbage is tender but retains its color.

Add the cabbage to the pan with the potatoes and swede. Add the remaining 25g/1oz butter and mash together using a potato masher. Season, to taste, with salt and freshly ground black pepper.

Place the mashed vegetables into an ovenproof lidded dish and top with the cheese. Cover with a lid and bake in the oven for about 30 minutes, then remove the lid and continue to cook for a further 15 minutes, or until piping hot and golden-brown on top.
