Add the whisked yogurt and using a fork, lightly mix everything together until it clumps together. Using your fingers, bring the mixture together and lightly knead it into a dough. The dough should be on the stiffer side, but moist enough to be rolled into a ball. The dough will also not be smooth (like pastry dough) which is fine. Do not overwork the dough , as this will develop the gluten and you will not get the flaky texture in the finished Balushahi.
