I found this idea on Pinterest and thought it was fascinating. Of course I had to try!
I used some green onions in my quinoa tabbouleh a few weeks ago, but instead of tossing out the white roots, I stuck them in a glass of water. Here they are on day one:
After a few days they started to shoot up!
Only a few more days later, they are just about ready to be used again. Wow!
The only negatives I see so far are that the onions are not growing back as big and thick as they were originally. That’s fine…I still have a free bunch of onions. Also, right at first there was a STRONG onion smell in our office! Haha! We don’t have a balcony or patio area, so I have to keep all my plants inside. I’m not sure I will do this indefinitely, but I read other bloggers who have grown onions 4 or 5 times from the same roots. So cool!
