Stir together the water, yeast, and sugar. Cover and allow the yeast to proof (or foam) for 5-10 minutes.
Stir in olive oil, salt, and flour. Knead for 5-7 minutes with a stand mixer or until smooth and elastic.
Remove the dough from the bowl, add the olive oil, and grease the sides. Return the dough to the bowl and turn to coat. Cover and raise for 60 minutes.
Punch down and turn out onto a floured surface. Divide into 8 pieces. Flatten each piece into a circle about 6-7 inches across.
Put about a ½ inch of oil in a cast iron skillet or heavy pot that is wide enough to fit your circles of dough. Use a thermometer and heat the oil to 365˚F. Carefully add a dough round to the hot oil. Cook for 3-4 minutes, flipping halfway through, until golden brown. Always monitor the temperature of the oil and stay close by the skillet.
