Dollop this verdant sauce atop our Dyed Deviled Eggs or Ramp Farinata, or use it to flavor our Roasted Leg of Lamb with Asparagus and Herbs.
Pulse ramps in a food processor until finely chopped. With motor running, pour in oil. Season generously with salt and pepper. To store, transfer pesto to an airtight container, pour a thin layer of oil over top, and refrigerate for up to 1 week.
For a milder pesto, blanch the whole ramps in boiling water for one minute before processing.
