To begin making the Kakrar Jhal Recipe, clean the crab with warm water and marinate with salt, turmeric and red chilli powder for 15 minutes.

Heat 2 tablespoons of oil in a frying pan and fry the crab pieces on a medium flame covering with a lid. Once it is crisp and nicely cooked, take out the fried crab pieces and keep aside.

In the same pan, add some more oil, heat it on medium flame. Add the potato with salt, turmeric and let it cook till the potatoes become a little soft for 5-7 minutes. Once it is done, take it out and keep aside. 

In the same pan, add cinnamon stick, clove and cardamom into the oil. Once they start sizzling, add onion paste and keep on stirring until it is cooked properly. This will take about 2 minutes. 

After 2 minutes, add ginger garlic paste and let it cook for another minute or two. Next, add all the dry spices including turmeric powder, cumin powder, coriander powder, red chilli powder, garam masala powder, salt and sugar. Mix them well.

After a minute, add tomato puree, green chillies and cook for about 2 to 3 minutes. At this stage, add 1/4 cup of water to avoid burning of the spices.

Finally, add fried potatoes and crab pieces and mix everything properly. 

Add required water (approximately 1/2 cup) and allow it to boil at medium flame for 8 to 10 minutes. Once done, switch off the gas and it is ready to be served.
