Making Korean Pickled Cucumbers (Oi-ji) – My First Homemade Jangajji
This is my first time making Korean pickled cucumbers (Oi-ji) using fresh cucumbers from Costco! I followed a simple recipe with sugar, salt, vinegar, and soju, and added garlic and chili peppers for extra flavor. After 7 days of fermentation, the result is a tangy side dish that pairs perfectly with rich meals. Here’s my beginner’s journey into Korean jangajji!
Hello there~
Today I’m sharing my story of making Korean pickled cucumbers (Oi-ji) using fresh Costco cucumbers.
Believe it or not, I’ve never tasted Oi-ji before in my life,
so this was my very first attempt at making it 😊
🥒 Starting with Fresh Costco Cucumbers
I picked up eight fresh cucumbers from Costco.
They were just the right size for pickling,
and I gently scrubbed them clean to avoid damaging the skin.
I trimmed off the stems,
and followed a recipe by CheonjaeSonyeon (천재소년).
I used 200mL of sugar and 100mL of salt.
The salt was a bit clumpy, so I used a fork to break it up.
🧄 Adding Garlic and Chili for Extra Flavor
Since Oi-ji is a type of jangajji (Korean pickled dish),
I figured garlic and chili peppers would pair well.
I added some whole garlic cloves and fresh green chilies from my kitchen,
plus two or three dried red chilies, sliced for extra kick.
I was really excited about this combo—
it felt like the perfect way to add depth and spice.
🧂 Mixing the Seasoning – Vinegar and Soju Finish It Off
- 200mL sugar
- 100mL salt
- 200mL vinegar
- 100mL soju
Once all the dry ingredients were in,
I gave everything a good mix before sealing the lid.
My strong husband helped with the stirring—thank you! 😄
After sealing, I labeled the jar with the date using a kitchen marker.
Now it just needs to sit at room temperature for 7 days.
🔄 Fermentation – Flipping Once a Day
During the fermentation process,
I made sure to flip the cucumbers once a day.
It was amazing to see how much liquid came out over time!
I didn’t expect this much brine,
but it turns out the cucumbers release a lot of moisture naturally.
🍽️ Serving Ideas – Perfect with Rich or Greasy Dishes
I haven’t tasted them yet,
but I can already tell they’ll be perfect with grilled meat or rich dishes.
Oi-ji is all about that crunchy texture and tangy flavor.
Next, I plan to explore ways to serve them—
maybe in Oi-ji muchim (seasoned salad), bibimbap, or cold cucumber soup.
I’m excited to experiment!
💚 Wrapping Up
This was my first time making Oi-ji,
and it turned out to be easier than I expected—and really fun!
I’ll share another post once I taste it after 7 days.
What I learned from this experience is:
Trying something new can lead to joyful discoveries.
Wishing you a wonderful day,
and may your day be as crisp as a pickled cucumber 🥒
