Don't let cleaning vegetables hold up the rest of your prep. With this tip, your scallions will be ready in a snap.
For a fast and efficient way to clean scallions, use a paper towel instead of a knife. Wrap a paper towel around the stem of the green onion, then grip the onion and slide the towel down the stem, peeling off the top layer. Now, snap the root end off. This not only removes unwanted layers, but also grit and dirt particles.
