Ingredients you’ll need
- Cocktail cucumbers aka Persian cucumbers - these little cucumbers are perfect for this dish because of their small diameter and small seeds. It makes pickling go much faster!
- Korean red pepper flakes - an extremely common ingredient in Korean cuisine. It's more flavorful, slightly sweet and earthy, and lends any dish a vibrant red color. A must try!
- Rice wine vinegar - a delicate, slightly sweet vinegar with bright, crisp flavors that gives this salad its signature tang!
Step by step instructions
- Cut the cocktail cucumbers into ½ inch rounds. They will shrink a bit during the brine so avoid cutting them too thin. (Photo 1)
- Marinate the cucumbers with sea salt and rice wine vinegar. This 'quick pickling' allows them to absorb the salt and vinegar and draws out some of their liquid. This helps them keep their crunchy texture. (Photo 2)
- After 30 minutes, the cucumbers will have released some of their liquid and absorbed the marinade flavors. Rinse the cucumbers under running water twice and taste one cucumber piece. Depending on your taste, you may need to rinse them one more time. (Photos 3 and 4)
- Mix the dressing ingredients in a small bowl and add it to the cucumbers. Toss it gently and serve immediately. (Photos 5 - 6)
Frequently Asked Questions
Yes! I recommend using a cucumber that has a thin skin and minimal seeds. English cucumbers, kirby cucumbers, or pickling cucumbers make good replacements.
If your cucumber has a lot of seeds, I recommend removing them as it can make the salad too watery. You can also peel the skin if you find it too tough.
Store any leftovers in an airtight container and keep it in the fridge for up to 3 days. Keep in mind, the cucumbers will release more liquid the longer you store them and the flavors will get stronger the longer it sits.
I highly recommend you use Korean red pepper flakes because it gives this salad the beautiful red color it's known for. Korean red pepper flakes are more fruity, earthy, slightly sweet, and can be less spicy depending on the brand you get. It can be found in most Asian grocery stores or in the Asian food aisle of your grocery store.
You can substitute with other red pepper flakes but you won't get the vibrant, intense red color to the dressing. I would reduce the amount to half to start with depending on how spicy the substitute is.
