Take 2 large onions, peel them and slice them thinly.
In a bowl, add 200 grams of gram flour (besan), 1 teaspoon of red chilli powder, a pinch of asafoetida (hing), 1/2 teaspoon of turmeric powder, and salt as per taste. Mix well.
Add the sliced onions to the bowl and mix until the onions are well coated with the batter. If needed, add a little water to make a thick batter.
Heat oil in a kadai for deep frying. Once the oil is hot, drop small portions of the onion batter into the oil.
Fry the pakoras on medium heat until they turn golden brown and crispy.
Remove the pakoras with a slotted spoon and drain them on kitchen paper to remove excess oil.
Serve hot with green chutney or ketchup.
