1 Wash the potatoes and cook them for 20 minutes in salted water. Drain them, refresh them. Then, cut them in half lengthwise and dig them out slightly.
2 Wash and dry the chives, and chop half of them. In a bowl, whisk the ricotta with the cream, the juice of half a lemon and the chopped chives. Season with salt and pepper. Divide this preparation among the half potatoes.
3 Cut the salmon slices into pieces and place them on top of the ricotta cream. Tie a sprig of chives around them and serve as an aperitif or starter.
