Pastizzi are usually diamond-shaped or round(known as pastizzi tax-xema' in Maltese) and made with a pastry. The pastry is folded in different ways according to the filling, as a means of identification. Traditionally, ricotta pastizzi are folded down the middle, whereas pea pastizzi are folded down the side. In recent years, alternative pastizzi fillings have emerged, most notably chicken pastizzi, which can now be found in virtually all Maltese pastizzeriji alongside the two traditional flavors. Other short-lived or limited edition pastizzi fillings have included ricotta and truffle, Maltese sausage, and Nutella.
