For the crespelle, mix flour, 1 pinch of salt and 80 ml milk until smooth. Stir in the egg. Let the dough swell for about 10 minutes. Heat half the oil in a coated pan (approx. 20 cm Ø). If necessary, stir the dough with 20 ml (2 tablespoons) of milk until it is a little thinner.
Bake half the dough in a pancake, turning once. Bake the rest of the oil and dough to make another pancake. Let it cool down. Cover with salmon, roll up, wrap tightly in foil, chill.
For the soup in the meantime peel and finely dice the shallots. Melt the lobster paste in a pot and sauté the shallots in it. Add stock and juice. Bring to the boil and simmer for about 10 minutes over a mild heat, stirring frequently.
Add cream and bring to the boil briefly. Mix with a hand blender. Season to taste with salt and pepper.
Wash the dill, shake dry and chop. Cut each pancake roll into about 10 slices. Put them on 4 wooden skewers. Arrange soup with crespellespikes and dill.
