Alaska · Alutiiq cod and seaweed context; original modern adaptation
Food history and kitchen connections
The Alutiiq Museum describes ancient cod-processing evidence on outer Uganik Island and identifies rockweed among seaweeds eaten locally. This soup uses market cod and purchased nori, a different seaweed. Those ingredient connections do not establish the combined broth as a historical Alutiiq recipe.
Nori brings a light marine flavor without asking a reader to collect seaweed from a shoreline. It should be treated as a labeled commercial food and used in a modest quantity, not as a nutritional supplement. Potato provides body while allowing the broth to remain clear. Adding cod only after the potato is tender protects a delicate fish from a long simmer. The fish is cut into large pieces so it can be lifted on a spoon rather than dissolving completely. All of these are modern decisions. They make a practical soup while acknowledging that using a retail substitute is different from participating in a coastal community’s food gathering and preparation practices.
Modern adaptation: This is an original modern soup, with nori openly substituted for Alutiiq rockweed. It uses market cod, supermarket potato and onion, packaged stock, and lemon. Do not use unidentified or beach-collected seaweed, and do not interpret the source’s food account as instruction to eat raw seafood.

Yield: 4 light main-course servings · Prep 15 min · Cook 25 min (approximate)
Ingredients
- 1 tablespoon sunflower oil
- 1 small onion, thinly sliced
- 12 ounces potatoes, peeled and cut into 1/2-inch cubes
- 4 cups low-sodium vegetable stock
- 1 cup water
- 1 pound skinless cod, cut into 1 1/2-inch pieces
- 1 plain food-grade nori sheet, cut into thin strips
- 1 tablespoon lemon juice
- 1/4 teaspoon fine salt, plus more to taste
Method
- Warm oil in a soup pot over medium heat. Cook onion for 5 minutes, stirring, until softened without deep browning.
- Add potatoes, stock, and water. Bring to a simmer and cook for 12 to 15 minutes, until the potatoes are tender at the center.
- Meanwhile, check cod carefully for pin bones. Keep the pieces refrigerated until the vegetables are ready, and wash utensils after handling raw fish.
- Lower cod into the gently simmering broth. Cook for 5 to 7 minutes, depending on thickness, until the thickest pieces reach 145°F. Stir minimally to avoid breaking them.
- Add nori strips and simmer for 1 minute. Remove from heat and stir in lemon juice and salt. Taste before adding more salt, since seaweed and stock vary.
Substitutions
Pollock or halibut can replace cod, with timing adjusted to reach 145°F. Use only plain labeled edible nori; a highly seasoned snack product will change both sodium and flavor. Leave nori out if seaweed is unsuitable.
Serving
Ladle gently so each bowl receives intact fish pieces. Serve promptly, since holding a fish soup at a simmer will continue to firm the cod.
Storage
Refrigerate within 2 hours at 40°F or below and use within 2 days. Reheat to 165°F. Nori softens substantially on storage, so the texture is best on the first day.
Sources and evidence notes
- Alutiiq Museum: Cod: Describes ancient cod-processing evidence on outer Uganik Island and continuing fishing; no claim that this new dish is ancient.
- Alutiiq Museum Plant Gallery: Rockweed: Documents rockweed as food. Purchased nori is a different seaweed used here as an openly modern substitute; no raw seaweed harvest is instructed.
