Place all ingredients into a food processor or blender and let it do it's magic.
Add some more olive oil to help blend as needed or to reach desired consistency.
Serve with prepared dish, or store in a jar or container for later use. Additional olive oil poured over pesto will help protect it for saving. Fresh Pesto will not survive for long, so use up within 1-2 weeks.
Please note, this is a guideline for pesto. I do not believe there is a perfect breakdown, as it depends on tastes and preferences. Either way you will adjust everything based on how much basil you use and what consistency you like.
Feel free to add more garlic and/or parmesan, those are incredible ingredients. Add pine nuts if desired, or get creative with other ideas such as sundried tomatoes, roasted red papers or additional fresh herbs.
Either way, I'd LaLaLaLOVE to hear how it went, and ENJOY!
