Okinawa Soki: Savory Seaweed & Tofu Broth with Pastured Pork
A comforting, deeply savory broth featuring tender cubes of silken tofu, rehydrated wakame seaweed, and slow-simmered ground pastured pork. This dish delivers the umami richness of traditional Okinawan cuisine without refined sugars or industrial seed oils, relying instead on the natural sweetness of whole dates and the mineral density of sea vegetables.

A little context
Soki soba is the iconic dish of the Okinawan Blue Zone, traditionally made with pork offal and a broth sweetened with refined sugar. We honor this tradition by using lean ground pastured pork for a cleaner fat profile and replacing sugar with whole Medjool dates, which provide fiber and minerals alongside sweetness. The broth is built from scratch using kombu and dried shiitake mushrooms to capture the authentic umami without ultra-processed shortcuts.
The longevity story
This recipe leverages the polyphenol-rich compounds in wakame seaweed and the anti-inflammatory omega-3s from pasture-raised pork to support cellular health. The inclusion of silken tofu provides isoflavones, while the savory depth is achieved through natural glutamates in the broth rather than processed MSG or bouillon cubes. By using whole dates for sweetness, we avoid blood sugar spikes, maintaining the low-glycemic profile essential for longevity protocols.
Method
- 01
Prepare the Umami Broth Base
In a large pot, combine 2 L (8.5 cups) of water, the wiped kombu, and the rehydrated shiitake mushrooms along with their soaking liquid. Bring to a bare simmer over medium heat. Once small bubbles appear, remove the kombu immediately to prevent bitterness, but keep the mushrooms. Simmer gently for 20 minutes to extract maximum flavor.
- 02
Sauté Aromatics and Pork
While the broth simmers, heat the extra-virgin olive oil in a separate skillet over medium heat. Add the julienned ginger and minced garlic, sautéing for 2 minutes until fragrant. Add the ground pastured pork, breaking it up with a wooden spoon. Cook until the meat is fully browned and no pink remains, about 8 minutes. Do not drain the fat; it carries flavor and nutrients.
- 03
Combine and Sweeten
Add the cooked pork mixture, chopped Medjool dates, and coconut aminos to the simmering mushroom broth. Stir well. Lower the heat to low and simmer uncovered for 15 minutes. This allows the dates to dissolve naturally, infusing the broth with a subtle, complex sweetness and the pork with savory depth.
- 04
Strain for Clarity
Pass the entire mixture through a fine-mesh sieve into a clean pot or large bowl. Press the solids gently with a spoon to extract the liquid, then discard the solids (or save the mushrooms for a separate stir-fry). You should now have a rich, amber-colored, clear broth.
- 05
Finish the Soup
Return the clear broth to low heat. Gently slide in the cubed silken tofu and the rehydrated wakame. Simmer for just 3-4 minutes. Do not boil vigorously, as this will cause the tofu to break apart. The wakame will darken slightly and the tofu will heat through.
- 06
Serve Immediately
Ladle the hot soup into deep bowls. Top generously with fresh sliced scallions. Serve immediately while the broth is steaming and the tofu is tender.
Pro tips
- ✦When selecting kombu, look for pieces with a heavy coating of white powder; this is mannitol, a natural umami compound, not mold.
- ✦For the pork, source from a local butcher who raises pigs on pasture; the fat profile will be higher in omega-3s and lower in inflammatory omega-6s compared to grain-fed pork.
- ✦Do not skip the step of removing the kombu after the initial simmer; leaving it in too long releases a slimy texture and bitter tannins.
- ✦If you prefer a thicker broth, you can blend a small portion of the rehydrated shiitake mushrooms and stir it back in before straining.

Substitutions
- lean ground pastured pork → ground grass-fed beef or wild-caught ground venison (adjust cooking time slightly based on fat content; venison is leaner)
- coconut aminos → tamari (gluten-free soy sauce) (slightly saltier, reduce quantity to 2 tbsp if using)
- dried shiitake mushrooms → fresh shiitake mushrooms (use 100g fresh, sliced, but note the broth will be less concentrated in umami)
Storage
Store in an airtight glass container in the refrigerator for up to 3 days. The tofu may soften slightly upon reheating. Freeze portions without the tofu for up to 2 months; add fresh tofu when reheating.
What to serve with it
- Hot sencha green tea to enhance the polyphenol absorption
- A small side of fermented miso soup (check for no added sugar)
- Steamed bok choy drizzled with sesame oil
FAQ
Why use dates instead of brown sugar?+
Traditional recipes use refined sugar which causes rapid glucose spikes. Whole dates provide fiber, potassium, and magnesium, slowing the absorption of sugars and aligning with longevity protocols.
Can I make this ahead of time?+
Yes, the broth tastes even better the next day as the flavors meld. However, add the fresh tofu and wakame only when you are ready to serve to maintain texture.
