For the crepes
1 cup plain flour/maida
1/2 cup sooji/rawa
1/3 cup fine sugar
1/3-1/2 cup water
Few tbsp of oil for greasing the pan
For the stuffing
300 ml milk
100 ml condensed milk (you can adjust as per your desired sweetness)
1/2 cup crumbled mawa (you can increase this quantity to make it thicker and quicker)
Pour the milk in a wide mouthed pan and add the condensed milk. Bring it to a boil and then lower the flame. Keep stirring to avoid sticking at the bottom. Once it reduces a bit, add the crumbled khowa/mawa and continue stirring till it is completely dissolved and incorporated. The mixture will now be thicker than before. Continue stirring on a low flame till you reach a rabadi/custard consistency. Remove from flame and let it cool completely. You can prepare this kheer one day in advance and keep it in the refrigerator until you are ready to prepare the patisheptas. Just take care to cover it well when kept in the refrigerator.
In a bowl, mix the flour, sooji, and sugar. Add water very slowly and little at a time till you reach the consistency similar to dosa batter/crepe batter. Basically, it should be of pouring consistency. Let it rest for 15-20 minutes. The flour may absorb some water at this time and so adjust accordingly.
Heat a little oil in a pan and wipe off the excess oil with the help of a kitchen towel or the head of a brinjal or onion. Lower the flame and pour 2-3 tbsp in the center and spread it out with the back of the spoon into a circle. Increase the flame a little and let the batter cook on top. Now put a spoonful of the kheer towards one end of the crepe and with the help of a spatula, roll it up. Flip the top and let it cook on both sides of the roll. Remove from heat and place it in a plate. Repeat for the rest of the batter. If the pan gets too hot, sprinkle some water and grease again and continue with the process. Enjoy your rich and gooey Bong delicacy!
