Here is a great double-chocolate walnut biscotti recipe by Patricia Turo, born into an Italian family in the US, but now living in the Klosters ski resort in Switzerland. This recipe is therefore more in the spirit of Ticino, the Italian-speaking part of Switzerland.

Be careful about the quality of chocolate you use: Avoid buying the American chocolate chips in a bag. You’d be better off buying a bar of dark chocolate from your favorite local chocolate maker and crumbling it up into bits. The same goes for the cocoa powder. Make sure it is good quality, preferably from a good chocolate maker.
