Wash and dry 3 ounces of fresh basil (about 2 packed cups). Measure out 1/3 cup almonds, 2/3 cup light olive oil, 1/2 cup grated parmesan, 2 teaspoons lemon juice, 1/2 teaspoon salt, a dash of black pepper, and peel 2 garlic cloves.
Add the almonds and garlic cloves to a food processor. Pulse until finely chopped and sandy, scraping down the sides as needed. This helps the pesto blend smooth instead of gritty.
Add the basil, parmesan, lemon juice, salt, and black pepper. With the processor running, slowly pour in the olive oil and blend until smooth and cohesive, about 30–60 seconds.
Taste the pesto and adjust salt, lemon juice, or olive oil if needed. The pesto should look glossy and evenly blended, not chunky or separated.
