In a large mixing bowl, add 2-3 TBSP of warm water. To this add cumin, grated jaggery, hing.
Mix and let it rest for a while.
Meanwhile, if using the field beans / avarekai, simmer in lightly salted water for 10 mins or till soft, drain and retain that water.
Prep the onions and any other veggies as needed, see recipe ingredients above.
To this, add the Ragi flour, beans, grated veggies, onions,grated coconut and salt and mix well.
Do not add any extra water at this stage as the onions and salt will leave water.
Once the onions are well incorporated, add the coriander, curry leaves and green chillies and mix till the mixture resembles bread crumbs.
Now add little warm water (use the water from the boiled beans) a little at a time and make this to a pliable dough.
Once the dough is made, rub 2 tbsp of oil on this and cover this for about 20 mins.
If refrigerating the dough, cover oil all over and store in an airtight container.
If making immediately, divide the dough into equal portions
Grease a banana leaf / parchment paper / plastic sheet and take one portion of the dough at a time and flatten out using hands about 6-8 inches in diameter and slightly thick.
Make a small hole in the centre to ensure even cooking (See video).
Transfer this Rotti to a hot tava. Drizzle 1 tsp oil in the centre and ½ tsp around the circumference too.
Let it cook on medium heat for 3-4 mins
Once done, flip over and cook the other side too. Drizzle ghee or oil if needed
Serve hot with jaggery / veg kurma / white butter
