Grate the potatoes and onion into a bowl.
Add the flour, salt & pepper and mix well.
In a large, hot frying pan (add a few tablespoons of vegetable oil), form mini Rösti (approximately 2 teaspoons of mixture per Rösti) and fry until golden and crisp on both sides.
Remove from the pan and drain on kitchen paper.
Place on a serving platter of your choice and top with a dollop of cream cheese followed with a ribbon of smoked salmon and some fresh dill and a squeeze of lemon.
