Method
- Make the broth: place the chicken wings in a large pot (at least 6-quart capacity), cover with cold water, and bring to a boil over high heat; boil for 3 minutes, then drain the wings in a colander and rinse both the wings and the pot under cold water to remove scum, since this step is what keeps the final broth clear rather than cloudy and gray.
- Return the rinsed wings to the clean pot and add the 8 cups water, quartered onion, smashed garlic, and sliced ginger; bring to a boil over high heat, then immediately reduce the heat to low so the liquid barely simmers with just a few small bubbles breaking the surface.
- Simmer uncovered for 2 to 2 1/2 hours, skimming off any foam or fat that rises to the surface every 20 to 30 minutes with a spoon, and topping up with a little extra water if the level drops below the solids; the broth should slowly turn golden and smell deeply savory.
- Strain the broth through a fine-mesh sieve into a large bowl or clean pot, pressing gently on the solids to extract the liquid, then discard the solids; you should have about 6 to 7 cups of broth. Season the strained broth with 2 tablespoons of the soy sauce and the mirin, then keep warm over low heat.
- Soft-boil the eggs: bring a small saucepan of water to a boil, gently lower in the 4 eggs with a spoon, and cook for exactly 6 1/2 minutes for a jammy, still-soft yolk; immediately transfer the eggs to a bowl of ice water for 5 minutes to stop the cooking.
- Peel the cooled eggs carefully under a thin stream of running water, starting from the wider end where there's an air pocket, then place them in a small zip-top bag with the remaining 2 tablespoons soy sauce and 2 tablespoons water, and marinate in the refrigerator for at least 30 minutes, turning occasionally, until lightly tinted brown.
- Make the pork topping: heat the vegetable oil in a medium skillet over medium-high heat, add the ground pork, and cook for 5 to 6 minutes, breaking it into small crumbles, until browned and no longer pink, reaching an internal temperature of 160 degrees F; season lightly with a pinch of salt and set aside, keeping warm.
- In a small bowl, whisk the miso paste with about 1/2 cup of the warm broth until completely smooth with no lumps, since adding miso paste directly to the pot can leave stubborn clumps floating in the broth.
- Stir the smoothed miso mixture back into the pot of broth along with 2 tablespoons of the butter, whisking gently until the butter melts and the broth turns a rich golden-brown color; keep the broth warm over low heat but do not let it boil hard, since boiling miso broth can dull its flavor and aroma.
- Bring a separate large pot of water to a boil over high heat and cook the ramen noodles according to the package directions, usually 3 to 5 minutes, until tender but still with a slight chew; drain well in a colander, shaking off excess water.
- Divide the drained noodles among 4 large soup bowls, arranging them in a neat nest in the center of each bowl.
- Ladle the hot miso broth over the noodles in each bowl, using about 1 1/2 to 2 cups of broth per bowl, making sure the noodles are mostly submerged.
- Halve the marinated soft-boiled eggs lengthwise with a sharp knife wiped clean between cuts, and arrange one egg's halves on top of each bowl of noodles along with a portion of the cooked pork and a small pat of the remaining butter.
- Finish each bowl with a scattering of corn kernels, sliced green onions, and a strip of nori tucked along the side of the bowl, then serve immediately while piping hot.
Tips
Blanch and rinse the chicken wings before making the broth; this small step removes the impurities that would otherwise cloud the broth and give it a muddy, off flavor.
Whisk the miso into a small amount of warm broth first until completely smooth before adding it back to the pot, since stirring the paste in directly almost always leaves unpleasant clumps.
