How to make
Turn oven on to 360°F (180 °C). Prepare a flat tray, covered with baking paper.
Boil the potatoes with their peels. Once ready, pour cold water over them, strain and peel. Mash to a coarse paste using a potato press.
On a coarse grater, grate the mozzarella, cheddar, feta cheese and add them to the paste. Sprinkle with the flour, salt, freshly ground black pepper, add the eggs and nutmeg. Stir until homogeneous.
Scoop a ball of the mixture with a large ice cream spoon and arrange in the tray on top of baking paper. Sprinkle each ball with olive oil on top. Bake at 360°F (180 °C) about 20-30 min. or until reddened on top.
Milk sauce:
To the thick yoghurt add the mayonnaise, salt to taste if needed, freshly ground black pepper, the pressed garlic clove, stir and add the chopped dill. Sprinkle with a trickle of olive oil for decoration.
Serve hot with this milk-garlic sauce.
