Chop basil, pine nuts and garlic with a sharp knife or mezzaluna, and add a pinch of salt .
Gently pour in the olive oil and mix to combine.
Add the Parmesan and freshly ground black pepper .
Transfer to a sterilized jar and cover the surface with a thin layer of olive oil. If you don't do this, your pesto will go dark and will not keep its beautiful green colour.
Store in the fridge
This will make one cup.
