Place potatoes in a large saucepan of salted water and bring to the boil. Reduce heat to medium and cook for 40 minutes or until tender. Drain and set aside for 5 minutes or until skins are dry and potatoes are cool enough to handle. Peel, discard skins and return to saucepan. Mash until smooth.
Meanwhile, heat cream in a small saucepan. Add to mashed potato and combine. Set aside in pan and keep warm.
Melt 60 g butter in a large saucepan over medium heat. Add spring onions and cook for 4 minutes or until softened. Transfer to a bowl, reserve pan and set aside at room temperature.
Add cabbage and 1 tsp salt to reserved saucepan with enough water to cover. Cook over high heat for 8 minutes or until starting to soften. Drain well in a colander, pressing on cabbage to extract as much liquid as possible. Add cabbage and spring onion mixture to mashed potato, stirring over medium heat until heated through. Season with salt and pepper, and spoon into a bowl. Make an indent in the top with the back of a spoon, slice remaining 65 g butter and place on top to serve.
