We placed the sprouting cloves (not very gently) sprout side up in some potting soil and gave them a little water. Then we put them on a shelf (out of reach) in our south-facing living room, where they would get a little warmth and light.
The garlic greens grew a noticeable amount every day. By the end of the week, they were about ten inches tall! So we had proved that they would grow, and the next step was to see if they were as tasty as I had heard.
We sliced a few up and put them in scrambled eggs. Our two-year old didn't eat them and my husband had a cold and couldn't taste them. I liked them more than I usually like scrambled eggs, though - they had a nice, mild garlic flavour throughout. So I will call the project a success!
I'm not sure if the greens will regrow from the bottom, or if I'll have to plant more cloves, but I will keep growing them. Apparently garlic greens are a good substitute for wild onions in recipes, and they are a staple in some types of ethnic cooking. They go well with eggs and cheese. Yum!
