Galaktoboureko is traditionally made with Fillo Pastry, but is equally as delicious when made with Kataifi Pastry. These individual serves of Kataifi Galaktoboureko are filled with a creamy semolina custard and topped with an aromatic Mastiha liqueur syrup. Mastiha liqueur is readily available from liquor stores, and can be omitted if you prefer to make a non-alcoholic version of this dessert.
