About this dish

Ego is a Fukushima seaweed jelly from Nishi-Aizu and Kitakata, made by dissolving egokusa seaweed through prolonged cooking and setting it in a square tray.

The seaweed is washed repeatedly, cleared of debris, and soaked before being stirred slowly over medium heat for 20 to 30 minutes. A little vinegar helps the fibers dissolve. When the thick mixture begins to spit and a spatula leaves a visible trail, it is poured into a mold and left to firm for one to two hours depending on the season. The set jelly is cut into the preferred shape and dipped in mustard soy sauce, traditionally appearing at memorials, Obon, New Year, and other gatherings.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

5 steps
  1. 1
    Step

    Rinse the dried egokusa several times under running water, carefully removing sand and pieces of other seaweed.

    Soak in clean water for 15 minutes to soften, then drain.

  2. 2
    Control

    Put the soaked egokusa and 600 ml water in a deep pot over medium heat.

    Once boiling, scrape the bottom slowly with a long spatula and cook for 10 minutes as the seaweed begins to dissolve.

  3. 3
    Control

    Add the vinegar and reduce to medium-low heat.

    Keep stirring slowly for 10 to 20 minutes, until no fibers remain, the thick mixture spits bubbles, and a spatula trail holds briefly.

  4. 4
    Prep

    Turn off the heat and pour the hot ego mixture into a shallow square mold, leveling the surface.

    Let the steam subside, then refrigerate about 2 hours in summer or 1 hour in winter, until firm through the center.

  5. 5
    Finish

    Unmold the firm ego and cut it into bite-size squares or thin noodle-like strips.

    Mix the mustard and soy sauce in a small dish and serve as a dip.

Tips

Thick ego mixture can spit as large bubbles burst. Use a deep pot and long spatula, and hold the heat at medium-low once it begins to spit.
Stopping while fibers remain gives the set jelly a stringy texture. Confirm both that no fibers are visible and that the spatula leaves a brief trail.
