Best Cucumber to Use

For the best results, use Persian cucumbers (aka mini cucumbers). They have a thin skin, minimal seeds, and a crisp texture, making them perfect for soaking up the flavorful sauce.

Dressing Ingredients:

  • Soy sauce: Adds a savory, umami depth. Tamari or coconut aminos can be used as a gluten-free or soy-free alternative.
  • Rice vinegar: Brings mild acidity, but if unavailable, apple cider vinegar or white vinegar can be used as substitutes.
  • Sesame oil: Use toasted sesame oil for a more intense flavor.
  • Sugar: Balances the salty and tangy flavors. Honey or maple syrup if you prefer natural sweeteners.
  • Garlic: Minced fresh garlic adds a sharp kick. Adjust to taste.
  • Toasted sesame seeds: For extra crunch and nuttiness.
  • Gochugaru (Korean red pepper flakes): Mild smokiness and gentle heat. Use less if you’re sensitive to spice or swap in red pepper flakes.
  • Optional: A spoonful of gochujang if you crave more spicy depth.

Prep the Cucumbers

Step 1: Slice your cucumbers thin, sprinkle with salt, and let sit for 15 minutes. This step helps remove excess moisture and ensures a crunchy texture. Don’t let it sit for more than 15 minutes, or it might get too salty. [Images 1 & 2]

Storage Tips

  • Refrigerate: Keep leftovers in an airtight container in the fridge for 1-2 days.
  • Drain Excess Liquid: Cucumbers release water over time, so drain any extra liquid before serving again to maintain crunch.
  • No Freezing: Freezing ruins the crisp texture, so skip the freezer!
