Not exactly Kushi Balti Chicken in the Instant Pot / Multi Cooker. (I will do it properly to assess how close it is.)
I've attached a photo of the ingredients after minimal preparation. From the lower left and in roughly clockwise direction.
Cassia Bark, Tej Pat, 2 cardamom, 2 cloves.
Kasoori Methi
Mixed Paste (2 TBSP each of Balti Paste and Mild Madras Curry Paste)
300 ml of water
Dried Coriander leaf (I didn't have fresh)
Blended in the Nutri-Bullet - 2 medium onions and about 30 grams of carrot with 1 TBSP of oil and a splash of water.
1 small can of Tomato Supreme. (Approximately 1 cup and any form of tomato will do)
Vegetable oil (I probably used 3 - 4 TBSP in total)
1.5 kg of large cut Chicken thigh fillet
1 TBSP Ginger 1 TBSP Garlic
1 tsp salt
1/4 each chopped red and green capsicum.
What I did:
I started by tempering the whole spices in oil in the instant pot on Saute mode. After a minute or so, I added the pureed onion and carrot and allowed it to simmer away for about 10 minutes, stirring to avoid catching.
While this was going, I used a small frypan on the cooktop to fry the garlic and ginger on low heat. To this I added the curry pastes and allowed to fry for about 2 minutes, then added the tomato and continued to cook on low flame.
I then removed the whole spices from the instant pot and poured in the frypan mixture, water and added the chicken, capsicum and salt.
Stir it up to combine and set on Curry mode for 15 minutes.
After completion I allowed to pressure down for 10 minutes before lifting the valve and opening the lid.
Add Kasoori Methi and Coriander and cook for a further 5 minutes on Saute.
Observations:
Again, don't add water or use a lot less, just to avoid initial sticking. (It is a non stick instant pot but

) I again needed to thicken with corn flour / water slurry as it was very watery consistency upon opening the lid. I think this is the biggest downfall of the method over pan fry BIR.
I forgot to include Garam Masala (from Kushi Balti). I added extra 1 tsp of salt after tasting following the pressure cook.
It made a nice mild chicken curry (Balti???) dish from scratch in less than an hour. It requires some tweaking but the method is solid. I used homemade pastes but you could use store bought of your choice for different profile dishes. Kashmiri, Rogan Josh etc. Some quartered fresh tomato added in the final 5 minutes would be OK as well.
