What you need:
For the outer covering:
All purpose flour - 1 cup
Gingely Oil - LOTS (I didn't really measure the exact amount)
Salt - a pinch
Yellow food colour or a tiny bit of turmeric powder
Mix all the ingredients together and knead into a smooth, pliable dough adding as much water as needed. The dough should be loose and elastic.. Don't stint on the oil if you want tasty, soft polis. Cover and let it rest for 3-4 hours.
For the filling:
1 cup channa dal
1 cup sugar
1 tsp cardamom powder
Pressure cook the dal with enough water. Drain all the water and grind it to a smooth paste along with the sugar. Take this mixture in a kadai, add cardamom powder and heat,stirring continuously, until all the moisture is absorbed.
To make poli:
Instead of patting the polis into a circle, you can roll them out with a rolling pin. If you choose to do that, use less oil. Make a dough that is the consistency of chapati dough and then roll out into circles.
Poli is traditionally made for Avani Avittam which falls on the same day as Rakshabandhan. So Iam sending this to Priti who is hosting Festive Foods-Rakhi-Thread of Love.
