Triple wash and soak long grain basmati rice for 20 minutes, later drain all the water, and set it aside.
In a blending jar, add mint, cilantro, ginger, garlic, green chili, salt, and blend it by adding 2-3 tbsp of water into the paste.
In the inner pot of an instant pot, turn on the SAUTE mode (Medium), heat 2 tbsp of oil, add black cumin seeds, and let them splutter.
Next, add peppercorns, cloves, cinnamon stick, a bay leaf, onions, and sauté for 30 seconds.
Add marinated soya chunks, blended puree, and sauté for 1 minute.
Transfer drained rice and sauté for 20 seconds. CANCEL the SAUTE mode, add 1 ¼ cup of water, mix, and adjust the salt at this point.
Close the lid on your Instant pot, making sure the valve is set to sealing.
Turn on the MANUAL/PRESSURE COOK button (High Pressure) and set the timer to 5 minutes.
Let the pressure naturally release (NRP) for 12-15 minutes.
Once the pressure is released, fluff the rice with a fork, and serve hot.
