Give the dried shiitake mushrooms a quick rinse. In a bowl, soak the dried shiitake mushrooms in at least 1 cup of hot water. Cover to let rehydrate.
8 dried shiitake mushrooms
In a large heatproof bowl, add the efu noodles. Pour boiling water over the noodles and let soak for 45-60 seconds, or until slightly softened. Alternatively, you can do this over the stove in a pot. Drain, then rinse in cold water to prevent it from becoming too soft. Drain again, then set aside.
8 oz efu noodles
Slice the scallions into 3 inch batons, separating the green and white parts. For the thicker white parts, slice in half vertically.
2-3 stalks scallions
Slice the yellow chives into 3 inch lengths. Mince the garlic.
1.5 oz yellow chives, 3 cloves garlic
Once the mushrooms have rehydrated, squeeze out all the water from them into the bowl. Remove the tough stems, then slice the mushrooms. Save the mushroom water for the sauce in the next step.
