Heat a small frying pan over a low heat. Cook the hazelnuts until starting to brown, shaking occasionally. Put into a food processor with the basil,wild garlic, parmesan, olive oil and garlic clove. Process until smooth and season with paper and lemon juice to taste.
Notes
Tip: If you haven't got some of the above herbs you can replace them with parsley, sorrel, coriander or rocket. I sometimes substitute half of the cheese with a different hard cheese such as cheddar, hard goats cheese, Emmental or Gouda.
