To make Tuscan cantucci, mix the sifted flour in a bowl with sugar, salt, liqueur to taste, eggs, and lastly the sifted baking powder. Quickly knead everything until the dough is smooth.
Then fold in the whole almonds. Shape into logs about 2 cm in diameter and place them, spaced apart, on a baking tray lined with parchment paper.
Bake in the middle of a preheated oven (electric, fan, or gas) at 150°C (300°F) for 25–30 minutes.
Once baked, cut the logs while still warm into slices about 1.5 cm thick, slightly diagonally.
Place the cantucci on the baking tray, cut side down, and bake for another 10 minutes at the same temperature.
After 5 minutes, turn them to the other side and finish baking.
