Mash the cooked and drained chickpeas in a bowl using a pestle or a masher until finely broken down. Ensure there is no excess water. Mash the cooled boiled potato separately.
Add the mashed potatoes to the mashed chickpeas. Then add cumin-coriander powder, chat masala, turmeric powder, chilli powder, salt, crushed ginger-garlic-green chilli, chopped onion, and chopped coriander leaves to the bowl.
Mix all the ingredients thoroughly until well combined.
Add cornflour and maida (or rice flour/only cornflour) to the mixture and mix again.
Take a portion of the mixture, make it into a round shape like a small ball, and then flatten it into a vada or patty shape. You can make them in small or large sizes.
Heat oil in a pan over medium heat. Gently slide the prepared vadas into the hot oil. Fry them on medium heat until they turn golden brown on both sides.
Once golden brown and crispy, remove the vadas from the oil and drain them on a tissue paper or in a strainer to remove excess oil.
The vadas can be served in various ways:As a standalone snack. In a bun like a burger. In a pav (bread roll) like a vada pav, with green chutney.Topped with curd, green chutney, date-tamarind chutney, chopped onion, chat masala, chilli powder, and sev. The vadas can also be shallow-fried on a pan with a little oil until golden brown.
Enjoy your homemade snack!
