Dough
Mix the flour, cheese and baking powder in a bowl. Whisk the eggs together with the pepper, salt and pesto, add to the flour along with the pistachios and almonds, mix quickly to form a dough.
To shape the biscuits
Divide the dough into 4 portions. On a lightly floured surface, shape each portion into a roll approx. 3 cm in diameter. Place the rolls on a baking tray lined with baking paper. Make sure they are well spaced out.
To bake
Approx. 20 mins. in the lower half of an oven preheated to 200°C. Remove, allow the rolls to cool slightly, then cut diagonally into slices approx. 2 cm thick. Return the cantucci to the baking tray, bake for a further 10 mins. Remove from the oven, leave the cantucci to cool on a rack.
