Author: Allison Jones


  • 125 g buckwheat flour
  • 75 g tapioca flour
  • 1 teaspoon baking powder (not baking soda)
  • 1 teaspoon finely ground sea salt
  • 1 cup (230g) tightly packed, mashed dark purple sweet potato - at room temp
  • 125 mL water
  • 2 tablespoons olive oil or more if needed
  • Oil spray as needed


  • Thoroughly mix together the flours, baking powder and salt in a medium-sized mixing bowl.
  • Put the mashed sweet potato in the food processor bowl. Add the oil and water to the mashed sweet potato and blend thoroughly, scraping down and re-blending if needed. The mixture should look smooth but may have some small lumps.
  • Add the bowl of dry ingredients to the food processor and thoroughly blend. Ensure all the ingredients are incorporated well. Remove from the food processor and ensure any stray oil or dry ingredients are removed as well.
  • Knead by hand gently for 2 minutes to ensure any stray oil or dry ingredients are fully incorporated. If the dough is sticky, wash and dry hands thoroughly and then add 1 teaspoon at a time of tapioca flour (up to 2 teaspoons) and incorporate well.
  • At this stage, any remaining stickiness can be addressed by adding in a little bit more oil - add in ½ teaspoon extra oil at a time up to 2 teaspoons.
  • Divide the dough in to two equal pieces and then divide each half again in to three or four balls depending on size and thickness preferred. Or, you can measure each ball instead (see notes).
  • Pre-heat a frypan on medium heat and spray with oil or add a small amount of other fat.
  • Place parchment paper on the bench, place one of the dough balls on top, ready to roll.
  • Place plastic wrap on top of the dough and roll the dough out to approx. 18cm (7") diameter. If you prefer, there is an easy method linked to in the Notes.
  • Remove the plastic wrap, set it aside and take the piece of parchment with the bread over to the frypan and flip it in to the pan so the parchment is on top and the bread is in contact with the pan.
  • Cook flatbread for 3 minutes and flip after bubble-lumps appear, then cook for another 2 minutes and then remove to a plate lined with paper towel or a cooling rack.
  • You can roll out each subsequent flatbread while one is cooking to save time.
  • Repeat until all flatbread are cooked.
  • Flatbread is best eaten fresh, but can be kept at room temperature for a day or so after cooking, covered in foil. They reheat well in the microwave with a sprinkle of water. The dough can be stored in the refrigerator for up to 4 days and brought to room temperature before using. The dough can also be frozen into individual flatbread balls and defrosted at room temperature when needed. Sometimes, the dough may need "refreshing" with a tiny bit of oil after it has been defrosted (it needs refreshing if it has cracks in it).


  • Equipment: Food processor, medium mixing bowl, one or two large non-stick frypans or skillets to cook the flatbread, wooden board, rolling pin, baking/parchmet paper, plastic wrap and a wide egg lifter.
  • If you want to use the dough for tortillas, use 50g of dough. If using for naan, flatbread or souvlaki, use 80g for a thicker flatbread.
  • See my tutorial here for making tortillas or flatbread easily. This is my preferred method as I'm not so great making a round shape with a rolling pin alone.
  • The cook time will be shorter if you use more than one pan for cooking the flatbread or if you want to make the batch of dough but only cook two immediately and use the rest of the dough later.
