Prep work - Soak the toor dal / tuvaram paruppu in water for about 10 to 15 minutes.
Turn the instant pot on sauté mode.
Add the Ghee and then when it heats up, add the mustard seeds.
In the meantime, grind together, tomato, ginger, black pepper, cumin, seeds, drained lentil (toor dal), and green chilies.
Add this to the instant pot along with turmeric powder, asafoetida, and salt. Mix well.
Add the washed and drained rice, and mix to combine. Now add the water needed. I used about 3 cups of water. We can adjust the consistency to make it runnier after the rasam sadam is done cooking.
Set the instant pot on pressure cook mode for 12 minutes.
I also placed a trivet and then placed some white rice to cook to use for Yogurt rice.
Once the instant pot turns off let the pressure release naturally.
Open the lid and carefully mix everything together.
If you prefer smoother and creamier rasam rice, gently mash everything together using a ladle.
Adjust the consistency of the rice by adding hot water. Again I used close to one cup of hot water to make my rasam sadam more flowing in consistency. At this stage also check for salt and adjust it.
Add the lemon juice and garnish with cilantro.
