Preparation Methods
Salting Cucumbers: Salting is a technique used to draw excess water from cucumbers, preventing a watery salad. To master this, sprinkle salt evenly and let sit for 10 minutes before rinsing.
Whisking Emulsions: This technique involves vigorously mixing ingredients like oil and vinegar to create a stable dressing. A steady hand and a small whisk are essential for a smooth emulsion.
Toasting Sesame Seeds: Toasting enhances the nutty flavor of sesame seeds. Use a dry skillet over medium heat, stirring constantly until golden brown.
Step 1: Prepare Cucumbers

Wash the cucumbers thoroughly.
Slice them thinly using a mandoline slicer for uniform slices.
Place the slices in a colander and sprinkle with salt.
Let them rest for 10 minutes to draw out excess moisture.
Step 2: Rinse and Dry Cucumbers

Rinse the salted cucumber slices under cold water to remove excess salt.
Pat them dry with a clean kitchen towel or paper towels.
Ensure cucumbers are thoroughly dried to avoid a soggy salad.
Place the dried slices in a large mixing bowl.
Step 3: Prepare the Dressing

In a small bowl, combine rice vinegar, soy sauce, sugar, and sesame oil.
Use a whisk to blend the ingredients until the sugar is fully dissolved.
Ensure the dressing is smooth and well-emulsified.
Taste and adjust seasoning if necessary.
Step 4: Combine Cucumbers and Dressing

Pour the prepared dressing over the cucumber slices in the mixing bowl.
Toss gently using tongs or a salad spoon to coat evenly.
Ensure every slice is coated with the dressing for maximum flavor.
Let the salad sit for 5 minutes to absorb flavors.
Step 5: Toast Sesame Seeds

Heat a small skillet over medium heat.
Add sesame seeds and stir constantly to prevent burning.
Toast until seeds are golden brown and fragrant.
Remove from heat and let cool before using.
Step 6: Add Garnishes

Sprinkle toasted sesame seeds over the salad for added crunch.
Add sliced scallions for a fresh, mild onion flavor.
Toss gently to distribute garnishes evenly.
Ensure garnishes are visible for an appealing presentation.
Step 7: Chill Before Serving

Cover the salad bowl with plastic wrap.
Place it in the refrigerator to chill for at least 15 minutes.
Chilling enhances the flavors and provides a refreshing taste.
Serve cold for the best experience.
Step 8: Serve and Enjoy

Remove the salad from the refrigerator and uncover.
Transfer to a serving dish for presentation.
Ensure the garnishes are evenly distributed on top.
Enjoy the salad as a refreshing side or a light snack.
