1/4 cup extra-virgin olive oil, plus additional if needed
1/4 cup grated Parmesan cheese (about 1 ounce)
1 garlic clove, minced
1 tablespoon toasted pine nuts
YIELD 4 servings
Combine the basil, oil, cheese, garlic, and pine nuts in a small food processor or blender. Pulse until a coarse paste forms, adding a tablespoon or two of water or more olive oil, if necessary to get a loose-enough consistency. Set aside 1/3 cup of pesto for this recipe; the remainder can be refrigerated in an airtight container for a week or so, or frozen for several months.
