步骤说明

1. 1

   Toast the pine nuts in a dry skillet over ^[medium-low heat], stirring frequently, until golden and fragrant, about 3–4 minutes. Watch them carefully — they go from golden to burnt quickly. Transfer immediately to a plate to cool.

2. 2

   Add the basil leaves, garlic, toasted pine nuts, and salt to a food processor. Pulse 8–10 times until coarsely chopped, scraping down the sides as needed.

3. 3

   Add the Parmesan cheese and lemon juice (if using). With the processor running, slowly drizzle in the olive oil through the feed tube. Blend until smooth but still slightly textured — about 30 seconds. Taste and adjust salt and black pepper. Set aside.

4. 4

   Bring a large pot of water to a rolling boil over ^[high heat]. Add the salt — the water should taste pleasantly salty, like mild seawater. This is the only chance to season the pasta itself.

5. 5

   Add the spaghetti and cook according to package directions until al dente — usually 8–10 minutes. Before draining, use a ladle or measuring cups to scoop out about 1 cup of the starchy pasta water and set it aside.

6. 6

   Drain the spaghetti in a colander. Do NOT rinse it — the surface starch helps the sauce adhere.

7. 7

   Return the drained spaghetti to the pot (off the heat) or transfer to a large skillet over ^[low heat]. Add the pesto and toss well to coat. Add reserved pasta water a few tablespoons at a time, tossing continuously, until the sauce is silky and coats every strand evenly. You may not need all of it.

8. 8

   Taste and adjust seasoning with salt and black pepper as needed.

9. 9

   Divide the spaghetti among warm bowls. Top with extra Parmesan cheese, a few toasted pine nuts, and a couple of fresh basil leaves. Serve immediately.
