Garlic scapes

Last spring I planted garlic purchased from Gourmet Garlic Gardens. On their site they said that after the scapes shoot up it will soon to be time to harvest. Had no clue what he was talking about. Now I do. This is a "scape". This photo take a couple weeks ago. Many of these scapes have blossomed and exposed myriad tiny garlic cloves. I figure this is some sort of flower and a method of propagation in the wild. The site mentioned that some gourmets harvest these scapes and cook them up as a delicacy. I sampled one of the little cloves. My gawd that was about the hottest, garlikiest thing I've ever eaten. Not really knowing what to do with the scapes I've just been cutting them off and adding them to the compost bin. I wonder if I'll get random garlic plants growing in my compost heap now?
