Pastilla (Besṭila), also transliteratedbastilla, bisteeya, b'stilla or bstilla is a traditional Moroccan dish inherited from the Andalus during the Umayyadempire.The name of the pie comes from the Spanish word for 'pastilla', after the transformation of the phoneme "p" into "b" that is specific to the Arabiclanguage. It is an elaborate meat pie traditionally made of squab (fledgling pigeons). As squabs are often hard to get, shredded chicken is more often used today; pastilla can also use fish or offal as a filling. Pastilla is generally served as a starter at the beginning of special meals.
It is a pie which combines sweet and salty flavours; a combination of crisp layers of the crêpe-like werqa dough (a thinner cousin of the phyllo dough), savory meat slow-cooked in broth and spices and shredded, and a crunchy layer of toasted and ground almonds, cinnamon, and sugar.
The filling is made a day ahead, and is made by browning the meat pieces in oil. The pieces are then transferred to a bowl, and with the remaining oil, onions, water, parsley, and various spices are cooked. The liquid is then chilled, and after, thickened to form a custard-like sauce with beaten eggs. The flesh and skin from the bones is shredded and added to the sauce, and it is chilled overnight.
In a round pizza pan, the first dough layer is added, and butter brushed onto it. The cook adds the sauce over the dough, and places two more sheets on top. It is then baked, sprinked with confectioner's sugar and perhaps more cinnamon, and served.
