Taken from For the Love of Cooking.
4 cucumbers, peeled, halved lengthwise and seeds removed
1 tsp salt
1/2 cup seasoned rice vinegar
1/2 cup of water
3 tbsp sugar
1/4 tsp crushed red pepper
2 tbsp minced red onion
1 tbsp chopped dry roasted peanuts
Peel the cucumbers then cut in half lengthwise. Take a small spoon and scoop out all the seeds from the cucumber. Cut into bite size pieces and put into a medium bowl. Sprinkle with salt and toss well. Combine vinegar, water, sugar, and pepper in a small saucepan; bring to a boil. Reduce heat, cook until reduced to 1/3 cut (about 10 minutes). Remove vinegar reduction from heat; cool. Stir in onion. Combine cucumbers and vinegar deduction in a medium bowl; toss well & sprinkle with peanuts (which I forgot to add before taking this picture).
I wasn’t sure if this would be too spicy for the kids with the red pepper but it was just enough to taste without adding too much heat.
