Add dried wood ear mushrooms into a small bowl and hot water to cover. Add dried lily flowers into another small bowl and hot water to cover. Rehydrate for 20 to 30 minutes, or until ingredients turn tender. Check after 10 minutes to make sure the water still covers all the ingredients. If the water gets cold, change to another batch of hot water. Gently rub with hands and rinse to remove the dirt. Remove tough ends of the mushrooms and flowers. Drain and place in a small bowl. It is OK if the ingredients are still a bit wet.
