This is one of the most popular appetizers at the dinner table in Japan, and it’ssimple and very easy to prepare in a short time.

What is Sunomono?

Sunomono (酢の物) refers to vinegar-based dishes, and they are commonly served as a side dish to the main meal. These light refreshing vinegar salads are a great start to any meal as the sourness from the vinegar helps whet your appetite.

”Su (酢)” means vinegar in Japanese, and when we mention “sunomono,” it typically refers to Japanese cucumber salad. During the heat of summer and our bodies naturally gravitate towards ‘cooling’ food, this cucumber salad makes a wonderful seasonal side dish, especially for grilled fish or meat.

It is tangy, crunchy, and so easy to whip up. Plus, its health benefits are good enough reasons to enjoy on a weekly basis.

How to Make Japanese Cucumber Salad

The Ingredients You’ll Need

• Japanese or Persian cucumbers
• Dried wakame seaweed
• Toasted white sesame seeds
• Dressing: rice vinegar, soy sauce, sugar, and salt

Substitutions

• Japanese cucumbers can be substituted with Persian cucumbers. Both of them don’t contain big seeds like American cucumbers. If you can’t find Japanese or Persian cucumbers, you can use an English cucumber, but scoop out the seeds with a spoon because seeds contain moisture that will dilute the dressing.
• You can skip dried wakame seaweed if you’re not a fan. You can read its health benefit in case you’re interested. Could’t find wakame seaweed? Try thinly sliced onion, radish, or carrots for a layer of texture and for additional nutrients.

The Cooking Steps

1. Rehydrate dried wakame seaweed in water for 5 minutes.
2. Cut the cucumbers into thin slices. Sprinkle the salt and distribute it evenly. Set aside for 5 minutes.
3. Squeeze out the liquid from the rehydrated wakame seaweed and cucumbers.
4. Make the dressing. Heat the dressing ingredients in a saucepan until the sugar is dissolved.
5. Combine the well-drained seaweed and cucumber, sesame seeds, and dressing, and mix them all together. Serve and enjoy!

3 Cooking Tips

1. Choose Japanese or Persian cucumbers. Avoid American cucumbers that contain big seeds and more moisture. Their skin is also waxy and thick, which is not ideal for this salad.
2. Generously salt the cucumbers. The salt helps draw out the moisture from the cucumbers so it does not dilute the salad dressing after mixing. This ensures a great crunch for the salad.
3. Squeeze out the liquid from the rehydrated wakame seaweed and cucumbers. If you don’t, the dressing will be diluted and the salad will have a bland taste.

Non-Vegetarian Variations

The recipe below shows the basic method of making sunomono. You can easily change things up and make variations of the salad by adding the following:

• Crab meat – I am unfortunately allergic to crab, so I used imitation crab meat in this recipe. I have a variation of the recipe here.
• Boiled octopus – I buy boiled octopus from a Japanese grocery store. It’s sold in the sashimi section and the package usually says “octopus sashimi.” You just need to cut it into very thin slices. I have a variation of the recipe here.
• Shirasu (boiled baby anchovies) – Baby anchovies are commonly used in Japan, and they are rich in calcium. If you live by the ocean and have access to anchovies, you should give this a try!
• Ground sesame seeds to the dressing – I have a variation here that I used spiralized cucumbers.

Enjoy the perfect balance of sweet and sour in this delicious cucumber salad!
