Biscotti della monaca are traditional Sicilian cookies originating from Catania. These S-shaped cookies were originally invented by the nuns of the Convent of Santa Chiara, who’d made them according to a secret recipe. The cookies are nowadays usually made with a combination of flour, sugar, margarine, ammonia, milk, anise, and salt.
The ingredients are kneaded into a dough that’s formed into balls, wrapped, and left to rest in the fridge. It is then rolled out and cut into strips that are formed into S-shapes. The cookies are baked in the oven, first once for ten minutes, and then once more for about twenty minutes.
