(makes 30 portions)
30 small, unblemished La Ratte potatoes
250g crème fraîche
Salt and pepper
Boil the potatoes in salted water till tender (about 15 minutes). Drain and cool slightly. Scoop out roughly one-third of the potato. Chop it quite small. Mix it with crème fraîche, chives and seasoning. Spoon the mixture back into the potatoes. Pile a little keta on top and decorate with a sprig of dill.
