1 large bunch of flat leaf parsley, stalks removed
6 large sprigs of mint (about 20 large leaves)
6 large sprigs of basil (about 20 large leaves)
2 cloves garlic, crushed
1 tbsp French mustard
6 anchovy fillets, rinsed
juice of half a lemon
56 tbsp extra virgin olive oil
PREPARATION:
1. If using a food processor, simply process the herbs, garlic, mustard and anchovies to a rough paste. Add the lemon juice and olive oil with the motor running until you have a thick sauce.
2. Alternatively, crush the garlic and anchovies in a pestle and mortar and stir in the mustard. Finely chop the herbs and mix in. Add the lemon juice and olive oil and whisk to a thick sauce.
3. Taste for seasoning and add black pepper if you like; it shouldn't need salt because of the saltiness of the anchovies.
