Sea Vegetables
Five Japanese, Korean, and Okinawan plates built on kombu, wakame, nori, and dulse
Sea vegetables are the only reliable food source of iodine, selenium, and the unique fucoidan polysaccharides that have moved cancer-prevention biomarkers in early human trials. Okinawans eat them daily — kombu in dashi, wakame in soup, mozuku marinated, hijiki simmered.
Five dishes that get sea vegetables onto your plate without forcing it.
In this issue
Crispy Agedashi Tofu with Polyphenol-Rich Dashi
This dish features silken tofu gently coated in organic buckwheat flour and flash-fried in high-smoke-point avocado oil until the exterior is golden and shatter-crisp, while the interior remains custard-like. It is served in a warm, umami-dense broth made from kombu and bonito flakes, seasoned with a touch of organic maple syrup instead of traditional sugar to balance the salty soy without spiking blood glucose. The result is a textural masterpiece that honors the Japanese concept of 'shun' (seasonality) while strictly adhering to longevity-focused nutrition.
30g proteinAji no Suka: Clay-Pot Baked Horse Mackerel with Purple Sweet Potato
This rustic Okinawan dish features wild-caught horse mackerel (aji) slow-roasted in a clay pot alongside vibrant purple sweet potatoes and fresh ginger. The fish steams in its own juices and a light brine of rice vinegar and kombu, creating a tender, deeply savory meal rich in omega-3s and anthocyanins without a single drop of refined sugar or seed oil.
Farm-Fresh Doenjang Guk (Korean Fermented Soybean Soup)
A savory, deeply umami-rich soup centered on traditionally fermented organic soybean paste, loaded with seasonal zucchini, shiitake mushrooms, and organic tofu. This version honors the gut-healing power of fermentation while eliminating refined sugars and industrial seed oils found in commercial shortcuts.
Savory Steamed Egg Custard (Chawanmushi)
Silky, savory egg custard steamed with homemade kombu dashi, pasture-raised eggs, and wild-caught shrimp. This breakfast dish delivers a gentle protein boost without the sugar crash, relying on natural umami from kelp and mushrooms.
Chawanmushi with Shiitake & Mitsuba (Japanese Washoku Tradition)
Silken steamed egg custard infused with homemade kombu-shiitake dashi, topped with earthy fresh shiitake and aromatic mitsuba. A savory, umami-rich lunch that honors the Japanese tradition of slow-steamed simplicity while adhering to sugar-free, seed-oil-free standards.
Buy kombu in big sheets, store in a dry pantry, lasts a year. One sheet = enough dashi for the whole month.
