To make pesto like in Genoa, Italy, you will need basil, pine nuts, parmesan cheese, salt, garlic, and olive oil. Blend the basil, pine nuts, parmesan, and 1/4 cup olive oil for 30 seconds. Then add a clove of garlic and 1/2 teaspoon salt and blend for 10 more seconds. The pesto can be frozen in plastic containers covered with olive oil to preserve its taste and health benefits.
