In a small saucepan, add 1-inch of water. Place steamer basket inside the pan and bring water to a boil. Add the egg to the steamer basket, cover with lid and set timer for 8 minutes.: You will notice the kettle like hiss as the water reaches a rolling boil and the steam begins to surge around the steamer basket, which signals that the egg inside is starting to cook evenly; this steaming method produces a tender, evenly set white and a slightly custardy center, which feels luxurious when you cut it open, and helps the yolk soak up broth flavor; avoid overpacking the basket or letting the water evaporate too low, because that can leave the egg unevenly cooked or create frantic splashing that cracks the shell.
In meantime, in a small bowl, stir the soy sauce and sugar together. Add in the bamboo shoots and mix well. Set aside.: Right away you will sense the glossy sheen form as the soy sauce melds with the sugar, making the bamboo shoots taste brighter and more savory; this quick pickle softens their bite while infusing them with seasoning so they play nicely with the broth; a common mistake is letting the mixture sit too long uncovered, which can dry the shoots, so keep it covered if you need to wait.
Empty the ramen soup seasoning package contents to a serving bowl.: When you open the packet, a concentrated aroma of miso and spices will hit you, and transferring it to the serving bowl lets the seasoning dissolve cleanly when you add hot water; this ensures no gritty clumps remain; do not pour seasoning directly into a pot of boiling water and overheat it, because intense heat can alter the flavor balance.
Bring another saucepan with 2 cups of water to a boil. Add in the dried noodles and cook for 4 minutes. When noodles are just about ready, add in the spinach leaves and stir. The spinach only takes a few seconds to cook. Ladle in the hot water from the saucepan into the serving bowl with soup seasoning. Stir well to dissolve the soup seasoning. Use chopsticks to add in the cooked noodles and spinach to the bowl.: As the water roils and the dried noodles hit the pan, you will hear a soft bubbling and see the strands separate, which tells you they are rehydrating correctly; when the noodles reach an al dente tenderness the bright green spinach will wilt instantly, collapsing into glossy ribbons that mix into the broth; ladling the hot water into the bowl releases the seasoning aroma and dissolves it into a silky broth, which is why you want to dissolve the seasoning in the bowl rather than the pot; overcooking the noodles here will make them mushy and they will soak up too much broth, leaving the bowl flat.
When the egg is done cooking, drain and rinse egg with cool water. Peel egg and slice in half. Serve miso ramen with egg, bamboo shoots, fish cake, corn, green onion and seaweed.: After cooling the egg you will feel the slightly firm shell ease away, revealing a delicately set white and a warm center that glows golden, and placing the halves atop the noodles creates a beautiful focal point and creamy burst with each bite; arrange the bamboo shoots , Japanese fish cake kamaboko , corn , sliced green onion , and pieces of roasted seaweed nori so they each sit in their own space, which makes each spoonful varied and pleasing; avoid layering everything without thought, because ingredients can become soggy or lose contrast if left to sit too long in hot broth.
