These tender shoots are sold fresh in Korean grocery stores. They have a bit of a garlicky kick and add flavor and color to many dishes in Korean cuisine. Scallions are an acceptable substitute, or the green part of green onions, or even spinach.
They dry out and go bad easily, so once I bring them home, I wrap them in a paper towel and then in a plastic bag before refrigerating. Stored that way, they will last a week.
