Ingredients:
1 cup - maida/all purpose flour
1 - ripe banana, medium sized
1 to 2 tbsp - curd/yogurt
4 to 5 tsp - sugar
1 tsp - jeera seeds
1/2 to 3/4 tsp - baking soda
1/2 tsp - salt
oil for deep frying


Method:

Mash the banana completely with your hands;
Add the rest of the ingredients, except oil, and make a dough;
The dough should be of the chapati dough consistency.
Note:
Be very careful while adding yogurt;
Yogurt gives out some water and tends to make the dough watery.
So, start with very little quantity and then add more, as required.
Cover and set aside for 4-5 hours.
Heat oil in a frying pan on low-medium heat;
A tiny ball of dough dropped into the oil should rise immediately - That's when the oil is ready.
Pull out ping pong sized balls of dough and pat them in between your palms to make pooris out of the dough;
You could also use rolling pin to make the pooris.
Note:
If you are using your hands for making pooris, greasing them with a few drops of cooking oil would help.
Drop the pooris in oil and deep fry on both sides until they turn brown;
Note:
While deep frying, press and keep them inside the oil for a few seconds, just like how you would do for ordinary pooris - This helps them fluff up!
Remove from oil and drain on paper towels;
Serve hot with coconut chutney/Sambhar and enjoy.
