Wash the rice 5-6 times or until the water runs clear. Drain and transfer to a heatproof bowl. Pour hot boiling water until the rice is fully submerged. Set aside and soak for 10 minutes.
Gently wash or wipe away any dirt on your mushrooms. Slice them up into strips or bite sized pieces. Set aside.
After 10 minutes has passed, carefully drain the soaked rice. Transfer the rice to a heavy duty pot like a clay pot or ceramic pot. Add 1 1/4 cup fresh hot water, neutral oil, soy sauce and give it a mix. Place the mushrooms on top of the rice.
Cover the pot and cook it over the stove top for 12 minutes. Bring it up to a boil over high heat first, then reduce the heat to the lowest setting. After 12 minutes, turn off the heat and keep the pot covered for another 10 minutes.
In the meantime, make the miso sauce by combining miso, soy sauce, sesame oil, honey, garlic cloves, and ground black pepper in a bowl. Stir and mix together well.
To serve, uncover the pot and pour the miso sauce directly on top. Garnish with scallions, mix, and enjoy!
