For Masala Vada Recipe, wash the chana dal well. Transfer it into a bowl and add enough water to immerse the dal. Soak the dal for about 2 hours.
Meanwhile, chop the onion, green chilli, mint and curry leaves. Keep aside.
Dry grind cinnamon, fennel seeds, red chilies and cumin seeds to a coarse powder. Transfer the powder into a small bowl and set aside.
After 2 hours, drain the soaked chana dal. Remove a handful of dal and transfer the rest into the same mixie jar.
Grind the dal coarsely without adding water. The mixture should be slightly coarse, not completely smooth.
Transfer the ground dal into a mixing bowl. Mix in the handful of soaked chana dal that was kept aside.
Add chopped onion, green chilies, mint leaves, curry leaves, ginger-garlic paste, salt and turmeric. Add the ground masala and mix well to combine all the ingredients evenly.
Heat oil in a deep frying pan over medium heat.
Take a small portion of the dal mixture and shape it into a round flat vada using your hands or a spoon.
Carefully slide the shaped vadas into the hot oil and fry them in batches.
Fry the vadas until they turn golden brown and crispy on both sides, flipping occasionally for even frying.
Once done, remove the fried vadas using a slotted spoon and drain excess oil on paper towels.
Serve hot and crispy Chana Dal Vadas with coconut chutney.
