Ken,
Those scapes picked at the right time are considered a delicacy in Korea. I had a friend at work with a Korean wife. He made big points taking a bunch of scapes home to her from my garden plot at work. She would chop them into short lengths and then do a light pickling. Here's a link to a recipe.

If you are going to try the recipe, don't let the scapes get too tough.
