1. What is Oi-Sobagi? (Instant Cucumber Kimchi) 🥒

Oi means cucumber, and Sobagi means stuffed. It is a type of Kimchi where vegetables are stuffed with spicy seasoning. Unlike cabbage Kimchi, it is meant to be eaten fresh or within a week.

It is packed with hydration and vitamins. Speaking of healthy vegetables, if you enjoy crunchy textures, you might also like Kohlrabi, another superfood that is great for salads!

3. Step 1: The Secret to Extra Crunchy Cucumbers 🔪

Nobody likes soggy Kimchi. The secret to keeping it crunchy is 'Boiling Salt Water'!

  1. Wash cucumbers and cut them into 2-inch lengths.
  2. Make a cross slit (+) in the middle, leaving about 1cm at the bottom connected.
  3. Boil salt water (2 cups water + 1 tbsp salt) and pour it directly over the cucumbers while hot.
  4. Let it sit for 20 minutes, then rinse with cold water and drain.

This method instantly hardens the surface, keeping it crunchy for days.

4. Step 2: Making the Spicy Vegan Stuffing 🌶️

Mix Gochugaru, Soy Sauce, Sugar, Garlic, and a little bit of water to make a thick paste. Then add chopped Garlic Chives (Buchu). The chives add a fresh oniony flavor that replaces the need for green onions.

5. Step 3: Mixing and Serving 🍽️

Gently open the cross slit of the salted cucumber and stuff the seasoning inside. Coat the outside with the remaining sauce. Sprinkle some sesame seeds on top, and you are done!

You can eat it right away, or leave it out for half a day for a slightly sour taste. Store in the fridge and enjoy within a week.


6. FAQ (Frequently Asked Questions) ❓

Q1. Can I use regular slicing cucumbers?

A1. Large slicing cucumbers have too much water and seeds, which makes the Kimchi soggy quickly. Use Kirby, Persian, or Pickling cucumbers for the best crunch.

Q2. Can I eat it immediately?

A2. Yes! Oi-Sobagi is a "Fresh Kimchi" (Geot-jeori). It tastes best when eaten fresh within 3-5 days. It gets soft and too sour if kept too long.

Q3. What can I use instead of Chives?

A3. If you can't find Asian Chives (Buchu), you can use Green Onions (Scallions) or thinly sliced onions. The flavor will be slightly different but still delicious.

Q4. Is this recipe Gluten-Free?

A4. Yes, provided that you use Tamari or a certified Gluten-Free Soy Sauce. Gochugaru is naturally gluten-free.

Q5. Why did my Kimchi become mushy?

A5. This happens if you didn't salt it enough or if you stored it for too long. Pouring hot salt water during the prep stage helps prevent this!
