Stuffed Artichoke Rösti with Brie, Bacon and Cumin

• 2 large potatoes
• 40 g (1½ oz) unsalted butter

Rösti is a Swiss grated potato cake fried in butter. My recipe goes one stage further, mixing Jerusalem artichokes, bacon and cumin into the potatoes and filling the cake with cheese. It makes a great accompaniment to poultry or meat dishes.

Boil the potatoes in their skins until just tender, about 20 minutes. Drain well and peel while they are still warm.
