Step 1: In a large bowl, whisk together the lukewarm water, yeast, and sugar. Let stand for 5 to 10 minutes until the mixture becomes foamy.
Step 2: Add 2 cups of the flour, the salt, and the olive oil to the yeast mixture. Stir until a shaggy dough forms. Gradually add the remaining 1 cup of flour as needed.
Step 3: Knead the dough on a lightly floured surface for 8-10 minutes until smooth and elastic. Place in a greased bowl, cover, and let rise in a warm place for 1 hour until doubled in size.
Step 4: Punch down the dough and divide into 8 equal pieces. Roll each into a ball and let rest for 15 minutes covered with a towel.
Step 5: Preheat your oven to 500°F (260°C) with a baking sheet or pizza stone inside. Roll each ball into a 6-inch circle.
Step 6: Bake the pitas on the hot stone for 2-3 minutes until they puff up. Remove and wrap in a clean towel immediately to soften.
