To make stuffing for this poli, heat a cooking pan adding sesame seeds. In medium flame roast them with constant stirring till they turn little brown. Transfer the seeds on to a plate and next add desiccated coconut. Roast the coconut as well for few seconds. Do not let it turn brown.
Take the roasted sesame seeds and de-seeded cardamoms in a mixer / blender and grind it for a while. Next include jaggery powder and pulse it again so that sesame seeds combines well with jaggery.
Finally add desiccated coconut and pulse it once again. The jaggery helps sesame powder to hold together, then divide it in to 10-12 lemon sized balls. Meanwhile make 10-12 lemon sized balls from rava dough too. Keep these ready to proceed with til poli.
Next take a dough ball in your palm, widen a bit with your fingers and then keep a sesame puran ball prepared in above step. Carefully cover the stuffing with dough and seal on top.
Next smear enough oil over a polythene sheet and roll the til stuffed dough in to medium thin discs of 4 to 5". Meanwhile heat a non-stick skillet.
Carefully lift the rolled til poli and transfer it over heated skillet. In medium flame let it cook. When bubbles start appearing, flip and cook till few brown spots show up. Remove it from skillet and continue the process with rest of the dough and puran.
Divine tasting til poli is ready to serve topping with a dollop of ghee.
