Got the recipe from my friend.
120 g butter
3 dl flour
1 tsp baking powder
2-3 tsp water
Mix them all until well combined, spread it on a baking pan (pie pan) and leave it cool while preparing the fillings.
Fresh dill (chopped)
Salmon fillet (cut into slices)
4 dl milk
Pre heat the oven at 200 deg C
Beat the egg, pour in the milk, add salt and black pepper to taste. Set aside.
Spread half of the chopped dill on the pastry layer.
Arrange the salmon in circular order (as in pic above)
Pour the egg mixture on top of the salmon. Spread the other half of dill
Bake the pie for 45 min (or until golden brown).
