For the pumpkin rösti with smoked salmon, coarsely grate the pumpkin and potatoes (with a rösti grater).
Place in a bowl, mix with eggs, flour, cornstarch, salt, pepper and nutmeg or season to taste.
Heat oil in a cast iron skillet, bake small hash browns until golden brown and drain well on paper towels.
Turn salmon into florets and arrange on plates with rösti.
Serve with crème fraîche and chives or onion rings.
