01 - Bring a large pot of generously salted water to a rolling boil. Add the pasta and cook according to package directions until al dente. Reserve ½ cup of starchy pasta water before draining in a colander.
02 - While the pasta cooks, place the wild garlic leaves, toasted pine nuts, grated Parmesan, and garlic clove into a food processor. Pulse several times until the ingredients are roughly chopped and combined.
03 - With the 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 - Add the drained pasta to a large bowl or back to the pot. Spoon the wild garlic pesto over the pasta and toss vigorously, adding splashes of the reserved pasta water as needed to achieve a silky, even coating.
05 - Divide among plates and serve immediately. Finish with extra grated Parmesan and freshly cracked black pepper if desired.
