Step by step

Prepare a sweet shortcrust pastry dough with the addition of a tablespoon of cocoa powder, then let the dough rest in refrigerator for 30 min.

Tips
Whilst you’re making the pastry, be careful not to let it get too warm: cool your hands, let the dough rest in the refrigerator, and then roll it out with a cooled rolling pin.
Trivia
According to legend, the tart was born in the Gulf of Naples where Partenope lived, and in whose honour the local inhabitants donated the ingredients (each with a different meaning) with which to make it.
