Boil the potato and peel the skin. Mash it very well and keep it aside.
In another wide bowl, measure the flour and add the rest of the ingredients except the water. Add one teaspoon of oil to the flour mixture and mix them all together.
Now slowly sprinkle warm water and start kneading the flour to form a soft dough. Do not add too much water as this does not need a lot and the potatoes have enough moisture.
You won't be able to make a perfect smooth dough and it will still be a little sticky. As long as the dough comes together, we are good.
Cover with a cloth and let it rest for 15 to 20 minutes.
Heat a griddle / tawa over medium to high heat.
In the meantime, divide the dough into 8 pieces. Form the pieces into a ball.
Dust the dough ball with more buckwheat flour and place it on a piece of
parchment.
Roll the dough into a medium thick flatbread. Don't make it too thin.
Place the rolled dough on the hot griddle and cook until it starts to brown. Flip to the other side and brush with oil. Do the same of the other side as well and cook until they are golden brown.
