Ingredients:
- 1 lb dried pasta such as fusilli or penne
- 2 tbsp sea salt for boiling water
- 3 cups fresh basil leaves, tightly packed
- 0.5 cup extra virgin olive oil
- 0.5 cup freshly grated Parmigiano-Reggiano
- 0.33 cup toasted pine nuts
- 2 cloves garlic, smashed
- 1 tbsp lemon juice
- 0.5 tsp black pepper
Instructions:
- Bring 4 quarts of water to a rolling boil in a large pot. Wait for big bubbles before adding the salt.
- Add 2 tablespoons of sea salt. The water should taste like the ocean to season the pasta properly.
- Add the pasta and cook for 1-2 minutes less than the package directions. Test a piece early; it should have a slight firm bite in the center (al dente).
- While the pasta boils, reserve 1 cup of the starchy pasta water using a heat safe measuring cup. Do not forget this step, as this water is your sauce's secret weapon.
- Drain the remaining water and keep the pasta in the colander for just a moment.
- In a food processor, pulse the basil, toasted pine nuts, garlic, and lemon juice until coarsely chopped. Stop before it becomes a paste to keep some texture.
- With the motor running, slowly drizzle in the olive oil. Watch for a thick, uniform consistency to form.
- Transfer the pesto to a small bowl and stir the grated Parmigiano Reggiano in by hand. Hand stirring prevents the cheese from getting gummy in the processor.
- Return the drained pasta to the warm pot (off the heat!). The residual heat from the pot is all you need.
- Add the pesto and half of the reserved pasta water. Toss vigorously with tongs until the sauce emulsifies and creates a glossy coating on every noodle. If the sauce feels too thick or looks dry, add the remaining pasta water a tablespoon at a time. You'll see the magic happen as the cloudy water and the oily pesto suddenly snap together into a creamy, cohesive sauce.
