What is Japanese cucumber?

Japanese cucumbers, called kyuri in Japanese, are thinner than English cucumbers and longer than Persian cucumbers. They generally do not contain seeds or have only very small, delicate seeds.

Can you use a different kind of cucumber to make sunomono?

Yes, you can use any cucumber you have access to. The best cucumbers for sunomono are the long, thin, seedless Japanese cucumbers, but you can substitute another type if those aren’t available.

Persian cucumbers are a good substitute because, like Japanese cucumbers, they have very few seeds and are thin with a tender outer skin.

English cucumbers will also work, but they tend to be more watery and have larger seeds, so you may want to halve them lengthwise and scoop out the seedy middle part before thinly slicing.

What ingredients are in Japanese cucumber salad?

Cucumbers, preferably Japanese or Persian cucumbers.
Rice Vinegar, preferably unseasoned. This can be found in just about any supermarket and, of course, in Japanese or Asian markets.
Soy sauce, just a touch!
Sugar, which balances out the tartness of the vinegar.
Salt, again, just a little.
Sesame seeds are optional. Black sesame seeds look dramatic, but white work well, too. You can also use a combination if you like.

How do you make sunomono?

Use sharp knife or a mandoline to slice your cucumber into uniform slices that are very thin.
Place the cucumber slices in a colander and toss them with a pinch of salt. This helps to draw out excess moisture and prep the cucumber to absorb the tart-sweet dressing.
Let the cucumber slices sit for a few minutes while you make the dressing. In a small bowl, whisk together the vinegar, soy sauce, and sugar.
In a medium bowl, toss the cucumber slices and dressing together. Let stand at room temperature for about 15 minutes, or chill in the refrigerator.
Just before serving, sprinkle toasted sesame seeds over the top.
Serve cold or at room temperature.

What to serve with sunomono?
