What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 2 whole Japanese or English cucumbers
  • 3 tbsp rice vinegar
  • 1 tbsp sugar
  • 0.5 tsp salt
  • 1 tsp soy sauce
  • 1 tbsp toasted sesame seeds

Step by step instructions

Step 1: Slice the Cucumbers

Slice the cucumbers into paper-thin rounds using a mandoline or sharp knife. Place them in a bowl and toss with salt, then let sit for 10 minutes.

Step 2: Remove Excess Moisture

Squeeze the cucumbers gently with your hands or press with a clean kitchen towel to remove as much water as possible then transfer to a clean bowl.

Step 3: Mix the Dressing

Whisk together rice vinegar, sugar, and soy sauce in a small bowl until the sugar completely dissolves.

Step 4: Dress and Serve

Pour the dressing over the cucumbers, toss to coat, and let marinate for 5 minutes. Serve in small bowls topped with toasted sesame seeds.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • rice vinegar → apple cider vinegar with a pinch of extra sugar
  • sugar → honey or agave syrup

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Skipping the salting step which leaves excess water that dilutes the dressing completely
  • Slicing the cucumbers too thick which prevents the vinegar from properly penetrating and marinating them
