Octopus salad with cucumbers in small bowls

Japan is an island nation surrounded by bodies of water. As a result, the Japanese have learned to enjoy many kinds of seafood in our cuisine. One seemingly exotic seafood is the octopus, my main ingredient for today’s recipe.

Outside of Japan, you can find octopus enjoyed in Asia, the Mediterranean, and South and Central America. Japanese don’t eat octopus at home too often, but it’s one of the key ingredients we use for sushi, takoyaki (fried octopus balls), oden (hot pot), and in an octopus salad called Tako Su (たこ酢).

What is Octopus Salad (Tako Su)?

Tako su is a type of sunomono (酢の物) or vinegar-based dish commonly served as a side dish to the main meal. For this salad, we combine thinly sliced octopus with crunchy cucumber, dried wakame seaweed, and toasted white sesame seeds, then toss it in a light and tangy Japanese vinaigrette. In my opinion, the contrasting colors and textures is a celebration of what nature provides us and a beautiful example of what good food is all about.

Making octopus salad at home is surprisingly easy if you can find sashimi or sushi-grade octopus (タコ刺身) in a Japanese grocery store. Even though we call it sashimi- or sushi-grade octopus, it’s actually boiled and ready to eat. To check if the precooked octopus is fresh, the skin should be dark purple and the flesh should be white. The texture is a bit chewy, but when sliced thin, adults can consume it easily.

I know octopus may not be for everyone, but I hope those of you adventurous eaters will give this salad recipe a try. It’s yummy and low in calories, making it a delightful side dish to serve especially for a midsummer dinner.

Instructions

  • Before You Start…Please note that this recipe requires 30 minutes of chilling time. 
    Gather all the ingredients.
    Octopus Salad 1
  • In a small bowl, soak ½ Tbsp dried wakame seaweed in warm water. Let it soak for 15 minutes. Then, drain and squeeze the liquid out. Set aside.
    Octopus Salad 2
  • Slice ¼ lb octopus sashimi (boiled octopus) very thinly.
    Octopus Salad 5
  • With ⅓ English cucumber, peel the skin lengthwise in a striped pattern, peeling ½ inch (1.3 cm) wide strips alternately with unpeeled sections. With this method, the cucumber slices have some decorative dark green accents and a little bit of extra crunchiness. Cut the cucumber into small pieces (I use the Japanese cutting technique called rangiri).
