If your scallions seem at all sandy, clean them like so: rinse the scallions and cut off the roots. Slice the white and green parts thinly, and put in a medium bowl filled with cold water. Leave for a few minutes, swishing them around a bit, letting any sand fall to the bottom. Scoop out the scallions with your fingers, leaving the dirty bits behind.
