Flash Marinate the or rather coat the lamb pieces very well with crushed pepper, flour, salt & turmeric (optional).
Switch on the Instant Pot & press the SAUTE button. Set it to HIGH.
Add olive oil. when the oil becomes hot add the coated lamb meat & sear very well on HIGH mode until nice & lightly brown. Don't worry about the bottom of the Instant pot getting brown, we'll sear it with red wine later & scrap the bottom well. If the "HIGH" settings becomes too much for you to handle then do switch back to the "NORMAL" mode. The searing process should take 6-7 mins.
Now, in the same pot add the chopped onion. Saute for a couple of seconds & add the minced garlic. Saute for a couple of seconds.
Next, add the red wine & de glaze the pot very well scrapping the bottom of the pan until that brown layer comes off.
Now add the seared lamb meat to the pot.
Add the veggies, chicken stock, bay leaves, pepper corns, salt to taste, fresh thyme.
Close the lid of the Instant Pot & seal the Vent. Press the MEAT STEW button. It'll automatically set for 35 mins. You are all done.
After 35 mins when the IP starts to Beep. Do a quick pressure release & open the lid slowly.
If you want to add a thickener then add now. Stir 2 tsp all-purpose flour in few tablespoons water until a slurry forms. Add it to the stew, stir well until fulli incorporated. Serve hot. Enjoy!
