About 10 min.
Preparation
Step 1
Heat a dry frying pan over a medium heat and add the pine nuts. Toast them for a few minutes, shaking the pan occasionally, until they are golden brown and fragrant. Remove from the heat and allow to cool slightly.
Step 2
Put the Parmesan chunks into a food processor, then add the basil leaves, garlic, toasted pine nuts and olive oil. Season with salt and freshly ground black pepper.
Step 3
Blend for a few seconds until the mixture comes together into a smooth pesto.
Step 4
Taste and adjust the seasoning, adding a squeeze of lemon juice if you like.
Step 5
If not using immediately, transfer the pesto to a jar and store in the fridge for up to one week, or spoon it into ice-cube trays and freeze for later use.
