Triple wash both the dals and soak them into 5 cups of water for 4 hours.
Drain the water and transfer them to the grinding jar or food processor.
In a grinding jar, add green chillies, cumin, turmeric, red chili powder, and salt.
Grind the mixture into a coarse texture by adding a very little water - around 3-4 tbsp if needed.
Transfer the dal mixture to a mixing bowl. Combine onions, coriander leaves, and mix everything well.
Line a plate with a paper towel to remove excess oil from the fried pakoras.
Add some Eno into the mixture and quickly mix it together. Do not overmix the batter.
Heat some oil in a kadhai (pan), on medium high heat. To check if the oil is hot enough, drop a small ball of a mixture in the hot oil. If it rises immediately that means the oil is ready for frying.
Once the oil is hot, lower the temperature to medium.
Take a small portion of the mixture with one spoon at a time and slowly drop it into the hot oil. Fry 6-8 small pakoras depending upon the size of your pan. Do not overcrowd the kadhai while frying the pakoras.
Flip the pakoras with a fork one at a time or with a slotted spatula once they turn golden brown for about 40 seconds.
Fry the pakoras until golden brown from the other side as well.
Transfer the pakoras to a lined plate using a slotted spatula to drain off the excess oil.
Repeat the same process until the mixture is finished and serve them hot.
