Pour water over shiitake mushrooms and place a small bowl on top of the mushrooms to submerge them in the water. Soak them overnight until softened. If rushing for time, use hot water. Don't discard the mushroom water!
Slice the softened shiitake mushrooms into thin slices (no need to discard the stalk).
Combine the sliced shiitake mushrooms, mushroom water, oyster sauce, sesame oil, light and dark soy sauce, and 500 ml water in a small pot. Cover and bring to a boil. Turn the heat down and simmer for 1 hour until the mushrooms are incredibly soft and infused with all the flavours.
Spoon the braised mushroom onto rice or tossed into your noodles.
NOTES
- You can simmer the mushrooms for a longer timing, just make sure the water does not dry up.- If the water is drying up while you are simmering, top it up with water to just cover the mushrooms.
