Step 1: Gather your ingredients. Ensure basil leaves are washed and thoroughly dried. Lightly toast pine nuts in a dry skillet over medium heat for 2-3 minutes until fragrant and golden, if desired. This step enhances their flavor significantly, crucial for many basil recipes.
Step 2: In the bowl of a food processor, combine the fresh basil leaves, toasted pine nuts (if using), garlic, and salt and pepper. Pulse several times until the ingredients are roughly chopped. This initial pulse helps break down the solids before adding oil.
Step 3: Add the grated Parmesan cheese to the food processor. Pulse again a few times to combine. The mixture should start to look like a coarse meal.
Step 4: With the food processor running on low speed, slowly drizzle in the extra virgin olive oil through the feed tube until the pesto is smooth and well combined. You might need to stop and scrape down the sides of the bowl occasionally.
Step 5: Taste the pesto and adjust seasoning if necessary. You might want to add more salt or pepper to your preference. The consistency should be thick but pourable. If it's too thick, add a tiny bit more olive oil. This is a vital step for perfecting any of your basil recipes.
Step 6: Transfer the pesto to an airtight container. If not using immediately, pour a thin layer of olive oil over the surface to prevent oxidation and keep it fresh.
