Wash cucumbers and slice them into thin rounds. Thinner slices = extra crisp vibes.
Sprinkle salt over slices, let sit for 5 minutes to draw out excess water, then pat dry.
In a small bowl, mix rice vinegar, sugar, and soy sauce until sugar dissolves.
Add cucumbers to the bowl and toss well to coat with the dressing.
Sprinkle toasted sesame seeds over the top for that subtle nutty crunch.
If using wakame, soak in water for a few minutes, drain, and mix in with cucumbers before serving.

How to Store

Keep leftovers in an airtight container in the fridge. They’ll stay crisp for up to 24 hours—after that, the vinegar works overtime and things get a bit mushy. IMO, it’s best eaten fresh while the cucumbers still sound like they’re auditioning for a crunchy ASMR video.

Why This is Good for You

Cucumbers are hydrating champs—about 96% water—so they help you beat the summer heat in style. Rice vinegar is gentle on the palate but also aids digestion, while sesame seeds bring healthy fats and minerals to the party. Light on calories but big on flavor? That’s the kind of health food I can get behind.

Pitfalls to Watch Out For

Don’t oversalt—unless you enjoy cucumber jerky.
Slice evenly; uneven cuts mess with texture and aesthetics.
Don’t marinate too long or your cucumbers will lose their crunch faster than a stale chip.

Variations You Can Try

Spicy Kick: Add chili flakes or a splash of chili oil.
Sweet Twist: Swap sugar for honey for a floral note.
Extra Umami: Add a splash of ponzu sauce.
Fruit Fusion: Mix in thin slices of pear or apple for sweet crunch.

FAQ

Can I use regular cucumbers?

Yes, but peel them and remove seeds for best texture. Japanese or Persian cucumbers are naturally thin-skinned and less watery.

Is rice vinegar necessary?

Rice vinegar gives authentic flavor. You can substitute with white wine vinegar, but the taste will be sharper.

Can I make it ahead of time?

You can prep the dressing and cucumbers separately, then mix right before serving to keep the crunch intact.

What can I pair it with?

Great with sushi, teriyaki, grilled salmon, or as a refreshing side to spicy noodles.
