I found an idea on Pinterest that seemed almost too simple and easy to be true. By placing the white ends of green onions in a glass of water, we could grow new green onions. This meant that we would have a steady supply of fresh green onions for practically free, considering we usually just tossed those root ends. After only few days in the water, the onions showed some promising growth:
And now, a month or so later, we've got more green onions than we know what to do with!
These taste just as good as the ones we grew them from, and so far we've expended no more effort than changing the water every few days. I was worried they might taste somehow watered down thanks to being re-grown, but that hasn't been the case. We've been able to use the entire green stalk that we harvest (I usually discard part of the greens from the store because they are too wilted).
We used the onions in this orange wheatberry salad, and in a few other dishes so far. This is definitely something I would suggest trying - although green onions aren't expensive, you can grow your own for practically free!
Do you have any tricks like this? Are there other kitchen scraps that can actually be re-grown?
