Cantucci are typical Tuscan biscuits, traditionally served with vin santo or red wine. They are also known as "Italian biscotti" because they are twice (bis) cooked (cotti). This version with dark chocolate is even yummier than the original!
This is the first time I’ve made a biscotti where I didn’t bake it twice, just put it in the shut-off oven for 30 minutes. I was worried that it would not have that crisp crunch that is so desirable in biscotti, but it did, wonderfully so. It was excellent. Next time I may add a few walnuts. - 24 Jan 2019 (Review from Allrecipes US | Canada)
