Prepare an ice water bath. Bring a pot of salted water to a boil. Drop in the ramp leaves and boil for 10 seconds. Immediately plunge into the ice water bath. Drain and squeeze out any excess moisture.Combine the blanched ramp leaves, Parmesan, and nuts in a food processor. Season with salt and pepper. Pulse to combine. With the motor running, drizzle in the olive oil. Blend until combined.
Note: I chopped and sautéed the ramp stem/bulbs in olive oil and then added as a garnish.
