Prepare the scallions by picking off any yellow stems.
Cut away the fibrous roots from the bottom.
Wash in cold water under tap, then cut the tops down to fit the skillet.
Heat the skillet and add the butter.
When the foaming stage is reached, put in the scallions.
Cover the skillet and cook over medium heat.
Turn them over after about 3 minutes.
Total cooking time is 4 to 5 minutes.
Be careful not to overcook; the white part should be a bit crisp, the tops tender, shiny, and green.
No salt or pepper will be needed.
