Not really. Even though filo pastry (also called phyllo or strudel pastry), flaky pastry and puff pastry are all made with the same basic ingredients of fat, flour and water, the proportion of fat to flour varies and this affects the amount of water used to form the dough and the type of pastry that results. If you use either flaky or puff pastry, both of which are sturdy, instead of the gossamer-thin sheets of filo, the results - although they may be satisfactory - will be completely different in texture.
Filo pastry can be made at home but it takes a great deal of time to beat, stretch, pull and roll the pastry into the characteristic sheets so thin you can read through them. It is much easier to buy it ready-made, fresh or frozen, either from supermarkets or from delicatessens.
Ready-made filo pastry comes in very thin leaves of varying sizes. Thaw frozen filo pastry thoroughly according to the instructions on the packet and let it come to room temperature in its box before you try to use it. The sheets should then be brushed with butter or oil before they are baked to make the pastry layers light and crisp.
