Take the Chopped Tomatoes in a mixer grinder jar and grind it to make a smooth tomato puree. Also grind the Chopped Onion to make smooth paste. You can grind them together if you want. I usually grind them separately. Keep them aside.
Now heat 2 tablespoon Oil in a kadai over medium flame. Add Cumin Seeds and Slit Green Chillies to it.
When the Cumin Seeds starts to crackle, add the Onion paste. Saute it till it turns slight golden in colour and starts leaving oil at the edges of the kadai.
Add Ginger Garlic Paste. Mix it and saute for few seconds till the raw smell of Ginger Garlic paste goes off.
Next add Tomato Puree and Salt. Mix the ingredients properly. Cook for 5-6 minutes or till the raw smell of tomatoes goes off. Keep stirring it at regular intervals so that it does not stick at the bottom of the kadai. Add Salt as required since we had already added Salt while pressure cooking the Chickpeas.
Now add the spices such as Turmeric Powder, Coriander Powder, Kashmiri Red Chilli Powder, Chole Masala Powder and Aamchur Powder. If you do not have Aamchur Powder, you can replace it with lemon juice. Add it before serving. Please visit Chole Masala Powder to prepare this masala powder at home. You can also use readymade chole masala powder.
Mix the spices with the Onion and Tomato paste. Saute them till the spices are cooked properly or the spices starts leaving oil at the edges of the kadai.
Now add the Boiled Chickpeas and combine it well with the spices. Cook it for 3-4 minutes.
After 3-4 minutes add the left over Chickpeas water to the chole. If required you can add extra water to it. Slightly mash the chole with the spatula to make the gravy thicker.
Cover the kadai and cook for about 5 minutes till the oil slightly separates with the chole. The gravy of the chole will become little thicker. Adjust the consistency of the chole curry as per your choice.
Lastly add Chopped Coriander Leaves and Kasuri Methi. Mix it and switch of the flame.
Now we will temper the Chole Masala. Heat Oil in a deep spatula. Add Slit Green Chillies, Slit Ginger and Asafoetida. Spread the tempering over the prepared Chole Masala. Punjabi Chole Masala is ready to serve.
