In a large mixing bowl, whisk together the gluten-free all-purpose flour, tapioca starch, salt, sugar, and instant yeast.
Pour the warm water and olive oil into the dry ingredients. Mix until a soft, sticky dough forms, about 2-3 minutes.
Place the dough in a lightly greased bowl, cover it with a clean kitchen towel or plastic wrap, and let it rise in a warm, draft-free place for about 1 hour, or until doubled in size.
Preheat your oven to 475°F (245°C). If you have a baking stone, place it in the oven to preheat as well.
Deflate the risen dough and divide it into 6 equal portions. Flatten each dough portion with your fingers into a disc about 1/4 inch thick.
Place the flattened dough rounds onto a parchment-lined baking sheet or preheated baking stone. Bake for 7-8 minutes, or until the pitas are puffed up and lightly golden brown.
Remove the pitas from the oven and let them cool slightly on a wire rack. Serve warm or at room temperature.

Notes
King Arthur Gluten-Free Bread Flour gives the best structure and puff; other blends may need more water and can bake up denser.
Start with ¾ cup (200 g) water and add more only a teaspoon at a time — the dough should stay soft and sticky, not pourable.
Fully preheat the baking surface for the full 30-45 minutes; an underheated surface is the top reason pita bakes flat.
Uneven puff is completely normal, even with the right flour and technique.
Don't skip the 10-minute shaped rest — it smooths the dough and helps it puff evenly.
This dough won't double during its rise; look for it to turn slightly puffy, not doubled in size.
