Wash the chives, dab dry and, except for a few stalks for garnishing, cut very coarsely. Wash, peel and coarsely grate the potatoes. Stir the chives, egg and flour into the potato mixture and season with salt and a little pepper. Heat some clarified butter in a pan.
Add small heaps to the pan with a tablespoon, press flat and fry until crispy brown on both sides. Keep the finished buffers warm and fry the rest of the mixture bit by bit. Arrange the buffers with crème fraîche and salmon on plates. Sprinkle with pepper and serve garnished with chives
