Mix the potatoes, flour, baking powder and salt in a bowl. Add the butter and rub together using your hands to form an even, crumbly mixture. Add the milk and honey, mix quickly to create a soft dough – do not knead.
On a lightly floured surface, roll out the dough to approx. 1.5 cm thick, cut out 12 circles (each approx. 5 cm in diameter), place on a baking tray lined with baking paper. Brush the scones with milk.
Approx. 15 mins. in the centre of an oven preheated to 200°C. Remove from the oven, leave to cool on a cooling rack.
Mix the crème fraîche and chives, serve with the scones along with the smoked salmon.
