03In a large heavy-bottomed saucepan, pour enough oil to fill the pan about 1/3 of the way. Heat over medium heat until a deep-frying thermometer inserted in the oil reaches 350 degrees F. (If you don't have a thermometer a cube of bread will brown in a couple of minutes.) Using a thin metal spatula, transfer the dough, 4 pieces at a time, into the hot oil, and fry until dark-golden and crispy, about 3 minutes. Drain on paper towels and roll in the cinnamon-espresso sugar while still hot. Transfer to a serving platter and serve immediately.
