Prepare the cucumbers and crab sticks. Tear the crab sticks into small pieces.

Wash the cucumbers thoroughly and slice them lengthwise into thin strips using a peeler.

Separate any stuck cucumber slices for better texture.

Place the sliced cucumbers in a bowl, sprinkle 2/3 tsp salt, and let them sit for 5 minutes. Rinse with water and squeeze out excess moisture.

Mix the cucumbers with crab sticks, a pinch of salt, 2/3 tbsp plum extract, 1 tbsp apple vinegar, and a pinch of sesame seeds.
