01 - Bring a large pot of generously salted water to a rolling boil. Add the pasta and cook according to package instructions until al dente. Reserve ½ cup of starchy pasta water before draining through a colander.
02 - While the pasta cooks, combine the wild garlic leaves, toasted pine nuts, grated Parmesan, and garlic clove in a food processor. Pulse several times until the ingredients are roughly chopped and combined.
03 - With the food processor running continuously, slowly drizzle in the extra virgin olive oil until a smooth, vibrant green paste forms. Add the lemon juice and season with salt and black pepper to taste.
04 - Transfer the drained pasta back to the pot or a large serving bowl. Add the wild garlic pesto and toss thoroughly, incorporating splashes of the reserved pasta water as needed to achieve a silky, even coating.
05 - Divide among serving plates immediately. Finish with extra grated Parmesan and freshly cracked black pepper if desired.
