Light, snappy, and amazingly cool, this classic Japanese cucumber dish brings a splash of sweet-sour flavor to your meals. The mix of super-thin cucumber slices with a just-right rice vinegar mixture makes a breezy side that freshens your mouth and adds some nice crunch to any Asian dinner.

Around our house, we can't get enough of this salad when the weather heats up. Even my kids, who usually turn their noses up at veggies, love to help slice the cucumbers and always want extra helpings.

Key Ingredient Picks

  • Persian or Japanese cucumbers: They give that must-have snap and mild taste this dish needs. With few seeds and thin peels, they really soak up all the good flavors
  • Rice vinegar: Gives a soft tang you just can't get from regular vinegar. Grab the plain kind so you can tweak the taste yourself
  • Regular white sugar: Works with the sour notes for that famous sweet-tart flavor. Skip fancy sweeteners as they'll change the traditional taste
  • Fine sea salt: Pulls out extra water, so your salad stays crunchy instead of soggy

Making Your Cucumber Dish

Getting Ready:
Rinse your cucumbers in cool water until they're clean. Look them over and cut off any bad spots or mushy parts.
Cutting Method:
Hold your knife slightly tilted against the cucumber. Make super-thin slices, trying to keep them all about the same size. Mind your fingers and try to get into a smooth rhythm for even cuts.
Salt Step:
Toss plenty of sea salt onto your cucumber pieces. Softly work the salt into them with your hands until they feel more bendy. Let them sit until water starts coming out.
Making the Mix:
In another bowl, stir rice vinegar and sugar together until all the sugar bits are gone. Run your finger through it - it should feel totally smooth with no grainy stuff.
Putting It Together:
Press the water out of your cucumbers with your hands. Pour your vinegar mix over them and gently toss everything so all pieces get coated.

Back when I was little, my grandma would make this salad every week, showing me why good knife work matters and how waiting patiently leads to the best texture.

Tasty Matches

This cool dish goes great with some grilled fish like salmon or mackerel for a real Japanese feast. It also works as a mouth refresher between different courses or can be lunch with some shrimp tossed on top.

Fun Twists

Jazz up this simple dish by mixing in some thin wakame seaweed strips for an ocean flavor, or add some shredded carrot for color and extra crunch. Want more protein? Top it with tofu rolled in sesame seeds or some cold chicken.

Staying Crisp

Keep your dish in a covered container in the fridge for up to three days. The cucumbers will get a bit softer but they'll still taste great. Just drain off any extra liquid before you serve what's left.

Frequently Asked Questions

→ Which cucumbers work best for this dish?
Japanese or Persian cucumbers are recommended since they’re crispy, have thinner skin, and fewer seeds. If you can’t find those, English cucumbers are a good backup.
→ Why salt the cucumbers first?
Salting removes extra moisture, helping the slices stay crunchy and stops the dressing from turning watery. This keeps the dish fresh.
→ How long will it last in the fridge?
You can keep it in the fridge for 2-3 days. The flavors actually improve over time, making it even tastier the next day.
→ Can this be prepared in advance?
Sure! Make it a few hours or even a day ahead. Just save the sesame seeds for right before serving so they stay crunchy.
→ Is it gluten-free?
Not with traditional soy sauce, which has gluten. Just swap it for tamari or a gluten-free soy sauce to make it work.

Ingredients

→ Main Ingredients

01 2 teaspoons salt (to pull moisture from cucumbers)
02 3 crisp Persian or Japanese cucumbers

→ Dressing

03 3/4 tablespoon (10g) sugar
04 1/5 teaspoon (0.65g) salt

06 2.25 tablespoons (31.5g) rice vinegar

Instructions

Step 01

Use a mandolin slicer (if you've got one) to cut the cucumbers into thin slices. Put them in a medium bowl.

Step 02

Toss the slices with two teaspoons of salt till everything’s coated. Let them rest for ten minutes so they release water.

Step 03

Wash the cucumber slices really well to get rid of the salt. Make sure to drain them fully.

Step 04

Give those cucumbers a good squeeze to get rid of all the extra water. Don’t worry about being rough—they're sturdy.

Step 05

Stir together the rice vinegar, sugar, soy sauce, and salt until everything dissolves completely.

Step 06

Pour the dressing over the cucumbers, and let the flavors mingle for at least an hour. Store overnight in the fridge, if you want.

Step 07

Right before eating, sprinkle on some sesame seeds for a little crunch.
