Take chickpeas in a bowl. Add baking soda and water. Keep aside for 5-6 hours.
Now, take them out of that water and wash them.
Add them to a pressure cooker. Add 3 cups water, 1 tsp salt, 1 bay leaf, 1 black cardamom, 2 green cardamoms, 4-5 black pepper seeds, 2 cloves, 1 tea bag, and 1 stick cinnamon. Mix them and cook them on high flame for about 15 minutes. You can wait for two whistles.
Then, lower the flame to medium and cook for another five minutes in the same closed cooker.
Now, take the teabag out and empty the contents of the cooker in a wide pan.
Add ½ tsp red chilli powder, 1 tsp coriander powder, 3 tsp channa masala, ½ tsp cumin powder, ½ tsp garam masala, ¼ tsp black pepper powder, and 2 tsp ginger garlic paste.
Mix it all thoroughly and cook for a few minutes.
Side by side, mash some of the chickpeas for the thickness in gravy. Now, add water according to your choice of thickness of gravy. Bring it to boil. Add some chopped green chillies and coriander leaves.
Remove the pan from heat and cover it with a lid.
Now, serve it in a bowl with Kulcha. You can serve them with tamarind chutney, finely chopped tomatoes, onions, green chillies, and coriander leaves on the side.
