Cold Cucumber Soup (Oi-naengguk: 오이냉국) English & Korean Captions

The written recipe and tips are here.
Are you looking for something refreshing, light, healthy, and cold cold cold? Yes, how about a cold cucumber side dish? In Korean it’s called oi-naengguk and it’s perfect for summer! The thin cucumber matchsticks soaked in icy cold, sweet, sour, salty, and garlicky brine will please your appetite. The cold temperature is a nice surprise and the crispy but soft texture of the cucumber is wonderful.
A great thing about this side dish is that you can make it in 5 minutes, and you don’t need to cook anything at all. Just cut the ingredients and mix.
Make this in the summer time, and I guarantee everyone will love it. My cookbook co-writer, Lauren, learned how to make this when she was recipe testing, and got a ton of stars from her family when she served it. They are all fans of oi-naengguk now, and when the book was done Lauren told me it’s one of her favorite Korean dishes. I was surprised!
I originally posted an oi-naengguk video years ago, but this one is a little updated and is a vegetarian version, and the video is HD. If you’re looking for the old one, it’s still here.
