Place a pot over medium-high heat and add the bacon. Render until crispy. Remove the bacon and set aside (this will be used as a garnish).To the drippings, add the ginger, garlic, and lemongrass and sauté for 1 minute. Add the red pepper flakes and stock and bring to a simmer, scraping up the brown bits on the bottom of the pan.Simmer for 30 minutes and then strain out and discard the aromatics (garlic, ginger, and lemongrass). Stir in the miso paste, soy sauce, vinegars, and toasted sesame oil and keep warm until ready to serve.Make the soft-boiled/poached eggs at this point but do not drain the water when finished. Instead, return the water to a simmer and cook the ramen noodles for 2-3 minutes or until tender. Drain, rinse, and set aside.To serve, divide the baby spinach, shallot, and the cooked noodles between two bowls. Ladle the hot broth over the noodles and top each bowl with the crisped bacon, soft-boiled eggs, scallions, and hot sauce. Serve immediately.
