Pesto Technique from Jamie Oliver

I used Jamie's Italy for guidance on my pesto last night.

The ingredient list was nothing special: Pine nuts, basil and Parmesan cheese in a 1:3:1 ratio with a clove of garlic and some olive oil. The technique was good, though. It recommends a three-step process:

1. Blitz the basil and garlic in a food processor then transfer to a bowl
2. Blitz the pinenuts and add to bowl
3. Add grated Parmesan cheese and olive oil slowly to achieve the required consistency.

By processing the basil and pine nuts separately, this technique allows both ingredients to be processed to the perfect texture.
