ROSTI

Steps:

• Place potatoes in large pot of cold water to cover and add 4 tablespoons of salt to pot. Slowly bring to a boil and then reduce the heat and simmer until tender. Drain and let cool. Refrigerate potatoes overnight.
• The following day, peel potatoes and grate into a bowl. Season, to taste, with salt and pepper and set aside. Heat 2 tablespoons of clarified butter in a medium saute pan over medium-high heat. Add 1 tablespoon of the unsalted butter and melt. Add leeks and saute until tender, about 5 minutes. Add crumbled bacon and set aside.
• For the first Rosti:
• Preheat the oven to 200 degrees F.
• Add half of the remaining clarified butter and unsalted butter to a small or medium non-stick saute pan and heat over medium-high heat. Add 1/4 of the potatoes and 1/2 the leeks and spread evenly over the top. Cover evenly with 1/4 more of the potatoes. Brown the potatoes for about 5 minutes and then place a plate over the top. Flip the potatoes over, and slide them back into the pan. Brown for another 5 minutes. Sprinkle 1/2 of the Gruyere over the top and melt. Remove from the pan and place in the oven to keep warm.
• For the second Rosti:
• Add remaining clarified butter and unsalted butter to the saute pan. Repeat the process with the remaining potatoes, leeks, and Gruyere. Serve immediately.

ROSTI WITH BACON, MUSHROOMS AND ONIONS

Steps:

• Boil the potatoes in their skins for 20 minutes, drain and leave to cool. Peel them. Using a cheese grater, grate them into a large mixing bowl and sprinkle with salt.
• In a frying pan saute the bacon and onions. Strip the leaves off the sprigs of thyme into the pan. Add mushrooms and cook for about 5 minutes until soft. Combine with the potatoes and mix gently, taking care not to mash them too much.
• Heat oil in a frying pan and add 3 or 4 spoonfuls of the mixture, See cook's note*. Using a spatula, pat the mixture into a round flat cake. Brown it over a high heat. When the bottom side is cooked flip it over. Repeat with remaining potatoes to make 6 cakes.
• Put 1/2 tablespoon of butter and a slice of Gruyere on each cake and melt under a hot grill or broiler. Turn the Rosti onto a plate and serve with a green salad, if desired.
