To toast the almonds
Spread the almonds on a tray.
Toast for approx. 5 mins. in the centre of an oven preheated to 200°C. Remove, allow the almonds to cool slightly, coarsely chop.
Combine the sugar, butter, eggs, egg yolk, wine, orange zest and salt in a bowl. Mix the flour and baking powder, add to the mixture along with the almonds, mix together to form a soft dough.
Divide the dough into 4 portions. On a well-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. Brush with a little egg white, sprinkle with sugar.
Approx. 30 mins. in the centre 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 5 mins. Remove from the oven, leave the cantucci to cool on a rack.
