Notes
Storage: To get your cut green onions to last longer, place them in a paper towel and run water through it until the water runs clear. Squeeze the excess water out of the onions and place on a dry paper towel and squeeze again to remove as much moisture as possible, let air dry for 10-15 minutes. Then store in a Tupperware lined with paper towelFor whole green onions that has not been chopped, try one of these two storage methods:
Storage Method 1: Place like a bunch of flowers in a glass jar covered by a plastic or silicon bag. You can trim the bottom of the sticks and be sure to change out the water every 3-5 days.
Storage Method 2: Roll the green onions in a clean, damp (not wet!) paper towel, then roll the whole bundle into a plastic or silicon bag.
