A little context

In Okinawa's Blue Zones, seaweed and fermented soy are staples for longevity, but traditional dressings often include refined sugar and processed oils. We honor the tradition by using date syrup for gentle sweetness and extra virgin olive oil for heart-healthy fats, preserving the umami depth while eliminating blood sugar spikes.

Why this food

The longevity story

Wakame seaweed provides iodine and sulfated polysaccharides that support metabolic function and gut microbiome diversity. Wild-caught shrimp offers lean protein and astaxanthin, a potent antioxidant that protects cellular membranes. Extra virgin olive oil introduces hydroxytyrosol and oleocanthal, reducing systemic inflammation, while garlic and ginger add antimicrobial and digestive support.

Method

01
Rehydrate the seaweed
Place the dried wakame in a bowl of cold water and soak for 10 minutes until fully expanded. Drain thoroughly in a fine-mesh sieve and pat completely dry with clean kitchen towels. Any remaining water will prevent crisping.
02
Crisp the seaweed
Preheat your dehydrator to 60°C (140°F) or oven to the lowest setting (approx 95°C / 200°F). Spread the dried wakame in a single layer on a tray. Dehydrate or bake for 20-30 minutes, checking frequently, until the seaweed shatters when bent. Do not burn.
03
Prepare the vegetables
While the seaweed crisps, julienne the daikon radish and carrot into matchsticks. Place them in a bowl, sprinkle with a pinch of sea salt, and let sit for 10 minutes to release excess water. Squeeze gently to dry before mixing.
04
Make the dressing
In a small jar or bowl, combine the tamari, date syrup, apple cider vinegar, extra virgin olive oil, grated ginger, and minced garlic. Shake or whisk vigorously until the oil emulsifies and the dressing is cohesive.
05
Assemble the salad
In a large mixing bowl, combine the dried shrimp, squeezed vegetables, and half of the dressing. Toss gently to coat. Add the crispy wakame last to preserve texture, then drizzle with the remaining dressing.
06
Serve immediately
Garnish with toasted black sesame seeds and sliced scallions. Serve immediately while the seaweed is still crisp alongside a protein or as a side to grilled fish.

Pro tips

✦Source wild-caught dried shrimp from reputable suppliers to avoid heavy metals found in farmed varieties.
✦Ensure the wakame is bone-dry before crisping; moisture is the enemy of crunch.
✦If you do not have a dehydrator, use the oven on the lowest setting with the door slightly ajar to let moisture escape.
✦Taste the dressing before adding salt; the tamari and seaweed provide significant sodium.
✦Make the dressing 1 day ahead to allow the garlic and ginger flavors to mellow and infuse.

FAQ

Why use olive oil instead of sesame oil?+

Traditional recipes often use sesame oil, but it is a seed oil that can oxidize easily. Olive oil is more stable and fits the Blueprint anti-inflammatory profile while still carrying the flavors well.

Can I make this ahead of time?+

The vegetables and dressing can be prepped 24 hours in advance, but add the crispy seaweed only right before serving to maintain texture.

Is the date syrup safe for blood sugar?+

Yes, whole date syrup has a lower glycemic impact than refined sugar and provides minerals, but for strict low-carb protocols, use monk fruit.
