Wash the asparagus, drain and peel the lower third. Cut off about 1 cm from the end. Cook the asparagus in boiling salted water for about 10 minutes. Meanwhile, wash the orange and dab dry. Finely grate half of the peel.
Cut the remaining peel into fine strips with a julienne chiseler. Halve the orange and squeeze the juice. Fill up orange juice with some water to 1/8 litre. Heat up the orange with the grated orange peel in a pot. Stir in sauce powder and bring to the boil. Stir butter gradually into the sauce over low heat. Season to taste with salt, cayenne pepper and sugar. Drain the asparagus and place in a greased, ovenproof dish. Pour the hollandaise sauce over the asparagus and bake in a preheated oven (electric range: 225°C/ gas: level 4) for 20-25 minutes.
