For the asparagus wrapped in bacon, bring a large pot with plenty of water to a boil and dissolve 1 tablespoon sugar and 1 tablespoon salt in it. Add the asparagus and cook for 10 minutes until al dente, melt butter and set aside.
Place egg yolks in a small saucepan and whisk over medium heat. Add the soup and continue to stir steadily. Slowly add the melted butter (should no longer be hot) to the egg yolks and continue stirring until the sauce thickens.
Season with salt and pepper, wrap the asparagus in several strips of bacon, and fry the bacon-wrapped asparagus in a large skillet until crispy on both sides.
