To make the potato purée, first boil the potatoes until tender and then peel. Push through a potato ricer or mash and then beat with an electric mixer before pouring over the melted butter and warmed cream. Beat well and season with salt and nutmeg. Set aside in a saucepan to keep warm.
Preheat oven to 200°C with top and bottom heat.
For the meatballs, mix thoroughly the minced meat, eggs, bread crumbs, salt, mustard, rosemary and garlic in a bowl and then use your hands to form into golfball-sized balls. Wrap in bacon and place in an ovenproof dish. Bake for 25 minutes.
For the browned butter, heat the butter in a saucepan and allow to bubble until it takes on a nut-brown colour.
When everything is ready, put a generous serving of potato purée onto two plates, serve the meatballs on top and garnish with browned butter and parsley.
Delicious accompanied by a freshly made cucumber salad.
