Wash both Rice and Lentils separately 2-3 times and soak them separately in water for 10 minutes.
In the meantime, roughly chop the onion and tomato.
If using Potato, remove the skin and cut it into halves.
Now take a clean pressure cooker and heat it.
Add mustard oil and heat it.
Temper the oil with Bay Leaf, Cumin Seed, 2 Dry Red Chilies, Green Cardamom, 10 Black Peppers, and also Cinnamon Stick.
The remaining black pepper and red chilies along with chopped garlic will be used at the end.
Once the spices start emitting an amazing aroma, add chopped Onion followed by potato chunks.
Fry those together till the onion changes color.
Now add chopped tomatoes followed by garlic paste and mix the spices.
Add 1 Tbsp. water and keep cooking till the mixture starts releasing oil from the edges.
Now add 1 Tsp. Salt followed by Turmeric Powder, Red Chili Powder, Cumin Powder, Coriander Poder, and also Sugar.
Give a thorough mix and add another tablespoon of water.
Keep the flame low and cook for a minute.
Now discard the water from the soaked rice and Red lentil.
Add both and mix thoroughly.
Cook for around 3 minutes on low flame.
Now add boiled pork chunks and mix those.
Add the pork stock (after heating) and mix.
At this point adjust the water content if needed.
The mixture should be fully soaked in stock or else add boiling water.
After soaking the mixture there should be water 2 inches above.
If needed adjust the salt at this point.
If you want the Khichuri spicy, add a few green chilies.
Now cover the cooker with a lid and put the vent weight.
On high flame cook till the cooker releases pressure one time (one whistle).
Now lower the flame and cook till the pressure cooker releases pressure one time (one whistle).
Switch the flame off and wait till the pressure drops completely.
Open the lid.
Check the consistency.
If you fill it in extra thick, add ½ cup or 1 cup hot water and cook for 2 minutes on high flame.
Lastly, heat Ghee in a pan and temper it with the chopped garlic and remaining dry red chilies, and black pepper.
Add this tempering to the Pork Khichuri and give it a mix.
Serve the Khichuri hot!
