Making pickles in this way is one of the simplest - you can make them in an hour if you are in a hurry. Even if the pickling time is only 2 hours, the pickled cucumbers are so tasty and full of umami. Specks of white grains from the koji are pretty on the green cucumbers.

Total Time assumes the pickling time is 2 hours, which is the shortest time.

Recipe Notes

1. I used 2 Lebanese cucumbers (similar to Persian cucumber).

2. You can find more about Shio Kōji, including where to buy it, in my post Shio Kōji Recipes – Pork Sauté and Pickled Cucumbers.

I used Shio Kōji in loose paste form, which contains broken rice grains. You can also buy Shio Kōji in a liquid form and use it in the same way. But I personally prefer using the standard Shio Kōji paste for marinade because the specks of white rice grains from Shio Kōji  .

3. Since Shio Kōji is slightly salty, the addition of mirin makes the pickling paste milder. But if you don’t have a sweet tooth like me, you might want to omit it.

4. Cucumbers Pickled in Shio Kōji can keep about 5 days in the fridge.
