In a wide bowl combine all-purpose, yeast, salt, sugar, cumin, turmeric, and yeast. Combine everything well.
Slowly add warm water and knead till you get a soft pliable dough.
Place dough in an oiled bowl. Set it in a warm area and let it rise and double in size. This takes about an hour or so. I always keep the dough for proofing in a preheated oven.
Once the dough doubles up, punch down and knead again. Divide into equal pieces of about 18 or so.
Dust well and using a rolling board, roll out into thick 6 inch discs.
Heat a Kadai with oil, gently drop into the hot oil and cook on both sides. The bara should puff up.
Once done, drain on a kitchen towel.
