Some days it’s not that you don’t want to cook; you just can’t stand battling oil and heat in a kitchen that’s pushing 90°F (32°C). In the sweltering summer, you simply don’t have the energy — and the last thing you want after eating is a pile of greasy pots and dishes to wash.
But you still need to eat. As they say, a happy stomach keeps you young. So you peek in the fridge and wonder: is there something light, cool, and easy you can toss together that doesn’t need a hot stove? One less stir-fry is one less reason to sweat.
And there it is, tucked in the corner: that everyday cucumber you always grab at the market. Nothing fancy — just a humble, budget-friendly cucumber waiting to be turned into a quick Japanese home-style side dish.
Give it a quick rinse, sprinkle with a bit of salt, and scrub the skin gently like an exfoliation. Rinse off the salt, slice it into bite-sized pieces, then add another pinch of salt to draw out excess water — even the cucumber has to sweat in this heat! :)
Next comes the seasoning: a pinch of shio kombu (salted seasoned kelp), a spoonful of mentaiko (spicy cod roe), and a drizzle of toasted sesame oil. Nothing overwhelms; every bite is perfectly balanced. It’s not the kind of taste that shouts, but the kind that makes you think, “Hmm, this works so well together.”
Mentaiko Marinated Cucumber isn’t a flashy Michelin dish — it’s real, savory, and refreshingly crisp; exactly the kind of Japanese side dish that cools you down on a sweltering day.
That’s it. Just toss it together, let it rest in the fridge for about 20 minutes, and it’s ready to enjoy.
There's no need for a special occasion or a good mood; when it’s this hot out, you just want something fresh and easy. This simple cucumber dish does its job perfectly.

Ingredients
📍Serves about 1–2 people
- 1 cucumber
- A pinch of salt (for purging excess water)
- A pinch of shio kombu (salted seasoned kelp)
- ½ teaspoon toasted sesame oil
- 1 tablespoon mentaiko (spicy cod roe, membrane removed)
- Extra salt to taste (optional)
How to Make It
- Prepare the cucumber: Lay the cucumber flat and slice crosswise at about 1/16 inch (2mm) intervals, but don’t cut all the way through — place chopsticks on both sides to help. Flip it over and repeat to create a crisscross “book” cut so the marinade soaks in better.
- Cut & purge: Chop the cucumber into bite-sized pieces about ¾ inch (2cm) long. Sprinkle with a pinch of salt and let it sit for 10 minutes to draw out excess water.
- Rinse & squeeze: Rinse off the salt and gently squeeze out excess moisture — be careful not to crush the cucumber.
- Season & mix: Add the shio kombu, sesame oil, and scraped mentaiko. Mix gently to combine. Taste and add a bit more salt if needed.
- Prepare the mentaiko: Use a spoon to remove the membrane and scrape out the roe before mixing.
- Chill: Transfer to a container and let it rest in the fridge for about 20 minutes so the flavors meld. Serve cold.
📍Tips
- If you don’t have shio kombu, you can substitute with a splash of light soy sauce and a few bonito flakes (katsuobushi).
- If you like a little heat, add a few drops of chili oil when mixing.
