The garlic scapes have arrived. The last time I saw them was three years ago, which was also the last time we grew garlic. Good luck finding these at a supermarket. In fact, I don't think I've even seen them at our local farmer's markets. Something tells me most of the general public wouldn't even know what to do with them. One great thing about growing your own vegetable garden is that you get to learn about, appreciate and in many cases utilize other parts of a plant like garlic normally considered waste in our commercial food production.
The best time to harvest scapes is when the stems are still curved. I usually cut them off a couple of inches above the tallest leaf. (You have to do this as the plant will develop a seed head, which draws energy away from the developing bulbs if you don't.) We've enjoyed them sauteed with other veggies. They also make a rather pungent pesto. I think using them in a pureed soup of some sort would also be nice. Just be prepared to wake up to the scent of garlic in the morning. But then again, there are far worst things in life for those of us who love garlic.
