Then knead on a floured work surface with floured hands to a smooth dough. Wrap in foil and chill for approx. 30 minutes
In the meantime peel the pistachios for the pesto, rub the skin of the pistachios between 2 tea towels. Coarsely grate the parmesan. Peel garlic. Wash parsley, shake dry and pluck the leaves from the stalks. Rocket, except for a few leaves for garnishing, clean, wash and drain well
Put about 3/4 of the pistachios, parmesan, 3 cloves of garlic and oil in a blender and chop finely. Add parsley and rocket, chop briefly. Fold in pistachio oil. Season to taste with salt and pepper
