In a large pot, heat 2 inches of vegetable oil to 360°. Working with 8 squares at a time, roll each square into a loose cigar and drop it into the hot oil. Fry over moderate heat, turning once, until golden and crisp, about 3 minutes. Using a slotted spoon, transfer the pastries to a paper towel–lined baking sheet to drain. Repeat until all of the dough is fried.
