Fillo dough de John Spottiswood

These are fragile, paper-thin sheets of dough that are usually basted with melted butter and then stacked until they're many layers thick. When baked, the combined layers make a rich, flaky, and crumbly crust. Greeks use phyllo dough to make baklava and spanakopita, while phyllophiles elsewhere use it to make pie crusts, strudels, Beef Wellington, egg rolls, and countless other concoctions. Some cooks use cooking spray instead of butter between the layers to trim fat and calories. The dough dries out quickly, so work fast once you've opened the package, and cover any unused dough with plastic wrap topped with a damp towel. Use fresh dough if you can find it; it doesn't tear as easily as the frozen kind. The frozen version is often wedged near the pie shells in the supermarket's frozen food case; let it defrost in the refrigerator for 24 hours before using it. Try Greek or Middle Eastern markets for fresh.
