Mersin Üçgen Yufka ~ 360g For preparing spring rolls without any mess or damage to pastry leaves. Phyllo (Pastry Leaves) is a very thin unleavened dough used for making pastries such as baklava and burek. Filo-based pastries are made by layering many sheets of filo brushed with olive oil. Filo dough is made with flour, water, and a small amount of oil or white vinegar though some dessert recipes also call for egg yolks. Though Phyllo"s roots are in Ottoman cuisine, the English term comes from the Greek name, which means leaf.
