Food storage tips that vegetable vendors will never tell you

4. Scallions
What should you do if you buy too many scallions and can't finish them? Actually, there are simple ways to preserve scallions.
Place the green onion roots side by side on a paper towel, spray a small amount of water on it to keep the paper towel moist. Then, roll up the paper towel. This will retain the moisture in the green onion roots and prolong their freshness.
Store the rolled-up scallions in the refrigerator, and after two weeks, they will still be as fresh as ever. This method is perfect for people who enjoy cooking but don't shop for groceries often, as it effectively avoids waste.
