To blanch asparagus: Bring a small pot of water to a boil and then add asparagus. Cook for about 3 minutes. Asparagus should be soft to bite, but not mushy when done. Drain the asparagus and immediately add asparagus to an ice water bath (or run under extremely cold water) to stop the cooking process and maintain the bright green color.
Alternatively, roast asparagus: Preheat oven to 375F. Toss asparagus in 1/2-1 tablespoon olive oil and distribute on baking sheet. Roast for about 20 minute, until soft, but not mushy.
