Method

1. Line a baking sheet with paper towels. Fill a large bowl with ice water.
2. Fill a large stock pot with water; stir in salt. Set over high heat; bring to a rolling boil. Blanch asparagus just until tender, about 3 to 4 minutes depending on asparagus thickness. Drain; immediately plunge asparagus into ice bath. Let asparagus chill for 3 to 5 minutes; place in a single layer on prepared baking sheet to dry.
3. Lightly spread a dab of cream cheese down center of each prosciutto rectangle; place asparagus stalks across narrow bottom end of prosciutto at a slight angle. Gently wrap prosciutto around asparagus so it covers stalks. Place asparagus on a serving platter; sprinkle with vinegar and season with several grinds of black pepper just before serving. Yields 1 asparagus per serving (depending on asparagus thickness).
