Score and Slice the Cucumbers
Using the tines of a fork, score the cucumbers lengthwise. This will help the dressing cling to the cucumber. (Feel free to skip this step if you're in a hurry.)
Slice the cucumbers thinly and place them in a mixing bowl. Toss the cucumber slices with the salt to help them release water, and let them sit while you gather the remaining ingredients.
Strain the Cucumbers
After about 5-10 minutes, strain the cucumbers using a fine mesh strainer (do not rinse). Transfer the cucumbers to a large mixing bowl.
Mix the Dressing
To the cucumbers, add the scallions, grated ginger, minced garlic, rice vinegar, soy sauce, sesame oil, maple syrup, and chili garlic sauce (or sriracha). Toss everything together to combine well.
Taste and Adjust
Taste the salad and adjust the seasoning as needed. You may want to add more salt or sweetness (maple syrup) depending on your preference. If you prefer more heat, add a bit more chili garlic sauce.
Serve or Refrigerate
Add the toasted sesame seeds and mix gently. Serve immediately or refrigerate until ready to serve. This salad is best enjoyed on the same day but can be kept for up to 3 days in an airtight container in the refrigerator.
