In a large mixing bowl, whisk together the cassava flour, salt, and baking powder. Break up any clumps so the mixture is evenly combined.
2 cups cassava flour, 1 teaspoon fine sea salt, 1 teaspoon baking powder
Pour in the olive oil (or avocado oil, melted butter, or ghee). Use a fork or your fingers to rub it into the flour mixture until it resembles a sandy, slightly damp texture.
2 tablespoons olive oil
Add 1 1/4 cups warm water to the bowl. Stir with a wooden spoon or spatula until the dough starts to come together. If it seems dry, add more water 1 tablespoon at a time. Let the dough sit for 1–2 minutes to allow the cassava flour to hydrate before adjusting.
1 1/4 cups warm water
Use your hands to bring the dough into a ball. It should be smooth, soft, and pliable, not cracking when pressed and not sticky like glue. If it is dry or crumbly, knead in a teaspoon of warm water at a time. If it is too sticky, sprinkle in 1–2 teaspoons cassava flour until it pulls away from your hands.
Cover the bowl with a clean kitchen towel and let the dough rest at room temperature for 10–15 minutes. This allows the cassava flour to fully absorb the liquid and improves the texture.
For flatbread or tortillas: Divide the dough into 8–10 pieces, roll into balls, and keep covered so they do not dry out. For biscuits: Pat the dough out on a lightly floured surface and cut with a biscuit cutter or glass. For a pizza or pie crust: Press the dough directly into a greased pan with your hands.
Heat a dry cast-iron or nonstick skillet over medium to medium-high heat. Roll each dough ball between pieces of parchment paper to about 1/8 inch thick. Cook each piece for 1–2 minutes per side, until small bubbles form and golden spots appear, adjusting heat so they do not brown too quickly.
For biscuits: Bake at 400°F (200°C) for 12–15 minutes, until lightly golden. For pizza or pie crust: Press into a greased 9–10 inch pan and pre-bake at 375°F (190°C) for 10–12 minutes before adding toppings or filling. For crackers: Roll the dough very thin, brush lightly with oil, sprinkle with salt, score into cracker shapes, and bake at 350°F (175°C) for 12–18 minutes until crisp.
