For cooking rice, add 1 tablespoon olive oil in the same pot and add small diced onions and cook them while continuously stirring until they are brown and caramelised.
Next, add in rice (I washed them before and drained out water).
Along with rice add in soy sauce, salt, green chilli sauce, black pepper and vegetable stock.
Mix to combine and cover it with the Instant pot lid.
Set the IP on high-pressure mode for 3 minutes and then for 10 minutes let it sit.
After 10 minutes, force release the remaining pressure and open the lid.
Add back caramelised mushrooms, chopped basil, scallions (if using) and mix gently and enjoy steaming hot mushroom rice.
