Below are tips on making Korean spicy cucumber salad recipe:
Combine sauce ingredients before mixing
Before adding your sauce ingredients to your cucumbers, mix it in a small bowl first. This will create a more even taste and makes the mixing process slightly easier.
Slice cucumbers thinly
By slicing them thinly, the sauce can penetrate the cucumber more thoroughly versus a larger piece.
For extra crunchy cucumbers
Sprinkle salt over the sliced cucumbers and let it sit for 5 minutes to remove excess water. Rinse the cucumbers under cold water and strain any excess liquid. Then mix in your sauce.
Chill cucumber salad for 10 minutes for best flavour
By chilling it for 10 minutes prior to consumption, this gives the dressing more time to absorb into the cucumbers.

All Korean grocers will sell it and you may also find it at larger Asian supermarkets.

Yes! Place the package in a resealable freezer bag and you can freeze it. It will last a very long time (up to a year!)

Yes! Any seedless cucumber will work for this recipe.
What can I substitute soy sauce with?

I love English cucumbers. In fact, I always have at least 2-3 in my fridge at all times. Your salad is such a lovely compliment to the flavors of the cucumber.
This simple yet complex recipe is a joy to behold. I love the variabilities in spice ability and just the great flavor.
Thanks for making my recipe! Glad you enjoyed it, Brett! Happy it hit the spot!
