Walnut and parsley pesto

Try this pesto as an alternative to the traditional pesto. It is great with pasta and also works well served on the side of grilled lamb chops or steak. 

INGREDIENTS

Serves four

100g walnuts

1 fat garlic clove garlic, peeled and roughly chopped

100g hard, mature goat's cheese (or Parmesan), grated

50g flat-leaf parsley leaves

About 150ml good olive oil (or extra-virgin rapeseed oil)

Juice of ½ lemon

Sea salt and freshly ground black pepper

METHOD

Put the walnuts and garlic into a food processor and process until finely chopped - but still with some granular texture. Add the cheese and process again briefly. Add the parsley and blitz again to chop the leaves, then begin trickling in the oil, while the processor runs. Stop when you have a sloppy purée. Taste, season as necessary with lemon juice, salt and pepper. If you don't have a food processor, you can make the pesto with a large pestle and mortar, crushing the ingredients together in the same order.

Store in the fridge - if you completely cover the surface of the pesto with oil so all air is excluded, it should keep for a couple of weeks.
