Pesto Recipe

Ingredients
½ clove garlic , chopped
Sea salt
Freshly ground black pepper
3 good handfuls fresh basil , leaves picked and chopped
1 handful pine nuts , very lightly toasted
1 good handful Parmesan cheese , freshly grated
Extra virgin olive oil
1 small squeeze lemon juice , optional


Method

1. Pound the garlic with a little pinch of salt and the basil leaves in a pestle and mortar, or pulse in a food processor. 
2. Add a bit more garlic if you like, but I usually stick to ½ a clove. 
3. Add the pine nuts to the mixture and pound again. 
4. Turn out into a bowl and add half the Parmesan. 
5. Stir gently and add olive oil – you need just enough to bind the sauce and get it to an oozy consistency.
6. Season to taste, then add most of the remaining cheese. 
7. Pour in some more oil and taste again. 
8. Keep adding a bit more cheese or oil until you are happy with the taste and consistency.
9. You may like to add a squeeze of lemon juice at the end to give it a little twang, but it’s not essential. Try it with and without and see which you prefer.
