Rinse the wild garlic well under cold water and check the leaves for any small insects. If you spot a few, that’s normal when foraging. Dry the leaves thoroughly with a clean towel - you don't want extra water to affect texture and shelf life.
Cut the leaves into rough pieces so they blend more easily. No need for precision
Spread the pine nuts in a dry skillet in a single layer. Don't use any oil. Toast over medium heat, stirring frequently, until lightly golden and fragrant. Remove from the pan immediately to prevent burning.
Grate or thinly slice the Parmesan into small pieces so it blends smoothly.
Place the wild garlic, salt, olive oil, and cheese into a blender. Pulse in short bursts until combined. The pesto should stay slightly textured, not completely smooth.
Scrape down the sides as needed and pulse again until evenly mixed.
