*sea salt
Heat olive oil or butter in a heavy skillet over medium heat. Add the onion, celery and garlic. Saute until the onion is browned and translucent. Add the mushrooms and saute until tender. Transfer all contents of skillet (including any liquid) to a large soup pot, add water and peppercorns. Place over medium-high heat and bring to a simmer. Season with small splashes of red wine and tamari to taste (keep in mind the salt in the tamari will intensify if you plan to reduce your broth). Lower heat to medium and simmer until broth reaches desired richness, 40 minutes to 2 hours. Adjust seasonings and add sea salt if needed. Strain broth through a sieve before serving.
Load soup bowls with cooked udon, scallions, cilantro, avocado, seaweed, soft boiled egg, poached fish, chili oil, etc. Pour hot broth over soup ingredients. Top with toasted sesame oil and sesame seeds. Serve.
