In a mixing bowl, combine the flours and a pinch of salt. Add one teaspoon of warm water and mix it with your fingers. Add another spoonful of water and mix more. The dough should be course and loose in texture, rather than moist. Add the water very slowly, in small increments, so that you don't end up mixing in too much. Puri dough should never be wet or sticky. If the dough seems very moist, work in some extra maida (or cake flour) to absorb the extra moisture. . Use your hands to knead the dough for about 7 minutes, until it becomes tight, stretchy and shiny. This will encourage the formation of gluten, which is essential to the texture of the finished puris. If the dough feels loose and falls apart, keep kneading. You should be able to stretch the dough without it breaking. If you wish, you can knead the dough using the dough hook attachment on a stand mixer. Pour the oil over the dough and knead it into the dough for another 3 minutes. This will improve the flavor and texture of the dough. Form it into a ball and place it in the a bowl. Cover the bowl with a damp dishcloth. Set the bowl in a dry, warm place. Let it sit for 15-20 minutes to rest. This will further improve the texture of the finished puris. Place the ball of dough on an oiled surface and use a rolling pin to roll the dough into a circle no thicker than 14 inch (0.6cm). The dough should be easy to roll thin without tearing. It may snap back when you attempt to roll it, but with a little work you'll be able to create a large, thin circle of dough. You can use a biscuit cutter or the rim of a cup. Cut out as many dough circles as possible from the rolled-out dough. Pour 2 inches (5.1cm) of oil into a stockpot or high-sided frying pan. Heat the oil until it reaches 400F (204C), or a bit of dough dropped into the oil sizzles and browns. When the oil is hot, place a few dough circles into the oil to cook. After just a few seconds), they'll begin to puff up and crisp. When they are crispy and very lightly brown (after about 20-30 seconds, use a large slotted spoon to place them on a plate lined with paper towels to drain. Continue frying the remaining dough circles. The puris will cook very quickly, so it's necessary to watch them the whole time they're in the oil. Remove them before they turn dark brown, or they'll have a burned taste and fall apart easily. Cook only a few puris at a time. If you crowd the pot, it will be difficult to control the cooking time of each puri. Don't cover the puris when they're finished cooking, or they won't stay crispy.

Summary:
Mix the flours with a few spoonfuls or warm water. Knead the dough well Add a teaspoon of oil and keep kneading. Rest the dough. Roll the dough very thin. Cut the dough into smaller circles. Heat oil for frying. Fry the puris.
