Rosti - Potato Cake
- 500g/1lb potatoes, parboiled whole, cooled and skinned
- 1 large onion
- Salt and pepper
- 50g/2oz butter
Grate the potatoes and onion, season generously with salt and pepper and mix well. Melt half the butter in a shallow frying pan and add the potato mixture. Flatten it down with a wooden spoon or spatula and cook over moderate heat for about 5 minutes until lightly browned.
Put a plate on top of the pan and turn the pan over so that the potato mixture falls on to the plate. Melt the remaining butter. Slide the potato back into the pan so that the underside cooks. Cook for a further 5 minutes or so. Slide on to a warmed serving plate. Serve at once.
