1/3cuppine nuts
1clovegarlic
1/2tspcoarse sea salt
1/2cupextra virgin olive oil (plus 1 tbsp to add on top)
Instructions
Gently wash basil leaves under cold water and drain them thoroughly until they are very dry.
In a food processor, blend Parmesan cheese, Pecorino Sardo cheese, pine nuts and garlic.
Add basil leaves and salt.
Continue to blend until you reach a smooth consistency, slowly drizzling the olive oil on top of the other ingredients during the process. Be careful not to over-blend the sauce or the blades will start to cook the basil.
Finally, transfer the pesto into a jar and cover it with some more olive oil to avoid oxidation.
