Sauté the onion in the olive oil until translucent then transfer to a mixing bowl.
Add the lemon rind, lemon juice, dill, crème fraîche-and-sour-cream mixture and half the grated cheese.
Beat the whole eggs and egg yolks well and whisk into the mixture.
Season to taste with milled sea salt and black pepper.
Drain the canned salmon well and stir the brine into the egg mixture.
Remove the visible bones and skin from the canned salmon and flake coarsely.
Mix with the smoked salmon pieces and then place the fish into the bottom of the pre-baked crust.
Pour the egg mixture over the fish and top with the remaining grated cheese and parsley, dill or fennel.
Bake in a preheated oven at 180 ºC for 35 – 45 minutes or until cooked but slightly wobbly in the center.
Remove from oven and allow to rest for 5 – 8 minutes before serving.
The ambient heat will cook and set the center during this time.
