1. On a steamer rack set over an inch of water in a saucepan, steam ramps, covered, until tender, 2 to 5 minutes. Transfer ramps to a work surface, and cut the leaves off, leaving a 4- to 5-inch stem.

2. Melt butter in a large skillet over medium heat. Add ramps, and cook, shaking pan, until ramps are warm and translucent, 4 to 5 minutes. Season to taste with salt and pepper; serve warm.
