Cut woody ends of both types into small pieces, cook in boiling salted water with sugar and 1 tsp. butter for about 15 minutes, drain. Keep asparagus warm. Heat 1 tbsp. oil in a frying pan. Pour in a quarter of the dough and spread. Bake for about 2-3 minutes on each side. Remove and keep warm. Cook crêpes in the same way and keep warm. Add sauce powder to an eighth of a liter of water and bring to a boil while stirring. Cut remaining butter into pieces, gradually whisk into warm sauce. Spread salmon evenly on crêpes, roll them up and cut into slices.
