Take 2 tbsp of gram flour (besan) in a bowl. Add water and mix it nicely. Keep it aside.

Now, take a wok or a frying pan and heat it on a low flame. Now, put 1 tbsp of white oil in it and when it heats up add 1 tsp of mustard seeds, 1 tsp of split black lentils (urad dal), and 1 tsp of split chickpeas (chana dal) in it. Stir them to fry them nicely for a couple of minutes until they start changing their color.

Now, add 1 tsp of cumin seeds and stir it as well.

Then, add 1 piece of dry red chili (torn in half), 2 to 3 pieces of fresh green chilies (broken in half), 1-inch fresh ginger (cut into thin julienne strips), and 8 to 10 pieces of fresh curry leaves to it and stir them to cook them nicely.

When these get reduced, add 1 piece of large onion (cut into thin slices). Stir it until it turns soft and translucent.

When they are done, add ¼ tsp of turmeric powder and ½ tsp of regular table salt to it and mix them nicely.

Now, add 1/8 tsp of asafetida to it and mix it nicely.

Add water and mix it nicely. Then, cover the wok to cook it on a low flame for about 5 to 6 minutes until it comes to a boil.

Remove the lid after 5 minutes to check whether the onions are cooked nicely or not. If they have, pour the mixture of besan into it and mix it nicely.

Let it cook for another 3 to 4 minutes until it becomes thick. Stir it occasionally and check the consistency.

When it is thick enough, mash 1 large piece of boiled and peeled potato and add to it. Mix it nicely and let it cook for another couple of minutes. (Pro tip: You may skip adding potato if you want. However, adding it will not only enhance the texture of the chutney but will also add to its taste.

When the chutney has become thicker, finally add a handful of fresh coriander leaves to it.

Turn off your gas stove and mix the coriander leaves nicely. Now, squeeze half a lemon (about 1 tsp of fresh lemon juice) directly into the chutney.

Mix it nicely, and transfer it to a bowl and your tasty homemade Bombay chutney is now ready to be served with hot puris, parathas, idli, dosa, and a lot of other dishes and snack items.
