Basil pesto darkens when exposed to air, so to store, cover tightly with plastic wrap making sure the plastic is touching the top of the pesto and not allowing the pesto to have contact with air. The pesto will stay greener longer that way.
Ingredients
- 2 cups fresh basil leaves, packed (can sub half the basil leaves with baby spinach)
- 1/2 cup freshly grated Romano or Parmesan-Reggiano cheese (about 2 ounces)
- 1/2 cup extra virgin olive oil
- 1/3 cup pine nuts (can sub chopped walnuts)
- 3 garlic cloves, minced (about 3 teaspoons)
- Salt and freshly ground black pepper to taste
- Special equipment needed: A food processor
