Destalk the basil leaves. Peel and chop the garlic. Break the cheese into pieces small enough to push down the feeder tube of the food processor.
Turn on the processor at full speed and work the cheese until it has the texture of coarse breadcrumbs. Do not over-process. Add the garlic and pine nuts and whizz briefly to incorporate. Stop the processor between each ingredient addition. Now add the basil and work again briefly until all the ingredients are evenly mixed.
With the processor working continuously, pour in the oil in a thin stream to achieve a thick oily paste. Taste and add salt and pepper as you like. Process again briefly to incorporate the seasoning and taste.
