Cantucci are very, very hard cookies meant for dunking into some liquid to soften them. More often than not that would be a small glass of vin santo (literally: sacred wine), a local liquor wine taking its name from its customary use for the Communion rite during Sunday mass. As a matter of fact, eating cantucci without it is considered extravagantly bizarre – and hazardous for your teeth. The secret of cantucci is that they are sliced off with a diagonal cut from a bread-like preparation when it is just out of the oven. This way the thermal shock caramelize the surface, hardening it. The inside however is made especially crunchy by huge quantities of toasted almonds and hazelnuts, hence their unique consistence.
