Pesto is very versatile. You can add it to freshly cooked pasta, spread onto white fish before baking, serve with grilled chicken or spread on bruschetta.
This homemade version is also much lower in salt than typical shop-bought pesto.
Heat a dry frying pan over a medium heat. Add the pine nuts and toast them for a few minutes until browned and fragrant.
Place the parmesan chunks in a food processor and add the basil leaves, garlic, toasted pine nuts and olive oil. Season to taste with salt and freshly ground black pepper.
Blend for a few seconds until it begins to come together and is smooth.
Taste the pesto for seasoning, and add a squeeze of lemon juice if you like.
If not using straight away, you can store the pesto in a jar and will keep for a week in the fridge. Or you can put it into ice-cube trays and freeze.
