2 cups of chopped potatoes place in your pressure cooker cover with cold water and set it for 1 minute to pressurise. Or you can just boil it in a pan.
Drain the potatoes in a colander and let it sit for a couple of minutes until the liquid has been drained fully. Reserve the liquid.

In a separate bowl, mash the potatoes with the 2 tbsp of ground flax seeds and salt until the mixture is smooth and consistent, then add the yeast mixture.
Keep mixing the potatoes and the yeast mixture, simultaneously adding gradually 1¾ cups + 2 tbsp of flour. Keep stirring until all the flour has been added. When the flour becomes difficult to stir, put it on a surface and knead it well until it turns into a dough. (Do not add any liquid).
Keep kneading the dough for 8-10 minutes until it’s soft and smooth texture. Cover the dough with the towel or put in a warm place for 45 - 50 minutes for rising and soft to touch.
