Rosti is supposed to be swiss dish. But very famous here in Germany also. And my children like it very much. For long I have been wanting to make this at home. Then sometimes back while browsing through DK's blog, Culinary Bazaar. I found this. To my surprise it involved very very less ingredients and so I immediately made it. It came out much better than the shop bought ones.
So here is the recipe. I did not make any changes. Just that she had made given the shape by putting it into a muffin form and I shaped it with my hands.
