The two-part challenge
Achieving the perfect Puran poli is no easy feat - it requires getting two textures just right simultaneously. The filling must be smooth, cohesive, and free of excess moisture; while the dough needs to be soft and stretchy enough to wrap around it seamlessly.
If one component is too dry, the dough cracks; if it's too wet, rolling becomes difficult.
Cook the dal until tender, not mushy
Make sure the chana dal is fully cooked but still able to be drained. Excess water can ruin the texture of the filling, so be sure to drain thoroughly before adding jaggery as directed in your recipe.
As the jaggery melts, the mixture will become more fluid. Keep cooking slowly until it reaches a thick enough consistency to maintain its shape. Remember to stir often to avoid burning.
Make the puran silky
Typically, the cooked filling can be strained through a puran yantra or other tool to achieve a uniform texture, but a different kitchen technique that results in a creamy, clump-free filling may also be used.
Infuse with cardamom and, if desired, a touch of nutmeg for added flavor. Allow the filling to cool before filling the dough.
Use a soft, rested dough
The dough needs to be more pliable than a regular roti dough. Different families use different types of flour, some mix flours, and techniques may vary by region. Allowing the dough to rest helps to evenly distribute moisture and makes stretching the dough easier.
Either oil or ghee can be utilized based on the recipe to achieve desired elasticity without any stickiness.
Stuff generously, roll gently
When making a puran poli, ensure the filling is ample. Flatten the dough, add a round puran ball, seal, and roll gently. Rotate often instead of rolling in one direction.
Use only the necessary amount of dusting flour; too much flour can cause the surface to become dry.
Cook until spotted and fragrant
Make sure to cook on a well-heated tawa, flipping when bubbles and light brown spots appear on the surface. Be careful not to overcook, as it can result in a tough texture. Serve while still warm.
The initial one or two may not be flawless. Consider them as a trial run: tweak heat, filling consistency, or dough softness before proceeding with the rest.
