Marinate the chicken and cordyceps flower for 10 minutes.
Rinse the rice and barley, and soak them in water for 10 minutes.
Add water and 1 tablespoon of oil to the claypot and cook over high heat. Bring it to a boil and add the rice and barley, and then stir lightly. Cover the pot, and turn the heat down to medium heat. Simmer until the water is all absorbed.
Place the marinated chicken on top of the rice. Turn down to low heat and simmer for about 15 minutes until all ingredients are fully cooked. Cook over high heat for 1-3 minutes.
