Select sauté to preheat the Instant Pot. When the word “Hot” appears on the display, add the oil. It should thin immediately. Pat the lamb cubes dry with paper towels and season generously with salt and pepper, then sear in the Instant Pot until browned on all sides, about 10 minutes. Add all of the jarred ingredients to the Instant Pot, along with the broth. Stir to mix. Cover with the lid and ensure the vent is in the “Sealed” position. Pressure Cook on High for 15 minutes. Allow the steam pressure to release naturally for 10 minutes, then release any remaining pressure manually.
