If garlic spears are what I think it is, it's used for banchan (side dish) in Korean cuisine among other things. The stems are pickled, cut into bite size lengths and then tossed in a chili power, garlic, seasame, seasame oil, sugar mixture. I've seen some recipes where it's incorporated into stir fry. I remember it was one of my favorite banchan because the garlic flavor is subtle and the crispy texture made it fun to eat.
