Authentic Japanese Cucumber Sunomono Salad Recipe

Different types of cucumbers

This recipe won’t work with the regular large cucumbers that you can find in most supermarkets. These cukes are too big, too thick, too loaded with seeds, too dry, and too hardy.

After trying these smaller, crunchier cucumbers, I have decided to give up on those.

To do it right, Japanese cucumbers are the best choice. Persian cucumbers work just as well. These cucumbers are more crunchy and have a thinner skin that you can leave on. Because they are virtually non-existent, you won’t need to remove them.

Japanese cucumbers are available at my local Japanese market, or Trader Joe’s for the Persian variety.

These cucumbers are now being sold in many American supermarkets. Although they are not the same variety, I don’t know if it is. They taste great and work well.

These other varieties are fine by me, as they offer organic cucumbers that may be more difficult to find at Asian supermarkets.

How to quickly slice cucumbers

Whatever method you choose, the ultimate goal is to get thin slices without using your fingers.

You can quickly slicing up these mandolin slices if you have some cut-proof gloves. It’s a hassle to wash the gloves, but it is worth it if you are making large batches. The cucumbers made with the mandolin slicer are beautiful and uniform.

Don’t forget your food processor. You can easily slice 8 cucumbers in less than a minute if your food processor has a thin slicer attachment with a feed tube.

I don’t shy away from cutting these byhand with a chef knife . But if you want to cut 300 of any item, it takes time to maintain consistency with the thickness. However, it is possible to cut the slices by hand using a knife. To keep the slices thin, make sure to use a sharp knife. You can also use a simple grater.

Double the recipe and keep one for the next day! It is much easier to make double batches than to do it all again when you need it. It will be a wise decision. If you plan to serve the dressing on another day, make sure to keep the dressing on the side. Once you are ready to serve, drizzle the dressing on top and then sprinkle with toasted sesame seed.

What is a Japanese cucumber?

Japanese cucumbers are shorter and thinner than the typical cucumbers that you find in American supermarkets. They are usually about 12 inches long, which is a little longer than Persian cucumbers but shorter than the large English cucumbers you often find wrapped in plastic wrap. Japanese cucumbers have the same green skin as other varieties.

The bumps are usually small and not prickly. They are mild in flavor and not bitter so you can use them as a salad ingredient or add dressing to your favorite salad.

Are Japanese cucumbers supposed to be peeled before being used?

The skins of Japanese cucumbers are thin and have a mild-sweet flavor. They don’t need to be peeled. You can create a visual effect by peeling some of the cucumber skin to expose the whiter interior. However, I prefer the look and it is very pleasant.
