To serve
Asparagus
Use a vegetable peeler to peel the asparagus stalks, working from the tops towards the ends. Sort the asparagus stalks by thickness and cut off the dry, woody ends with a knife. Bundle the stalks in portions and tie them together with butcher's twine. Bring a large pot of salt water to a boil, then add butter, sugar, white wine and more salt. Place the asparagus in the boiling water and cover the pot, leaving the asparagus to boil for about 12 minutes.
Bolzano sauce
Boil the eggs for 7 minutes, rinse them in cold water, peel them and separate the egg white from the yolk. In a bowl, combine egg yolk, mustard, salt, pepper and hot water and stir the mixture well. Stir in the oil slowly but vigorously. Season with white wine vinegar, then add chives and the finely chopped egg white.
To serve
Sprinkle grated parmesan and drizzle melted butter on top, then pour the Bolzano sauce over the dish. Add the boiled ham, chives and herb oil. Serve immediately.
