The original recipe is from here and I have made a few changes from the original one.I could not get Korean chili powder so used our regular chili powder and decreased the quantity of sugar.
Cucumber - 1 medium sized,thinly sliced
Rice vinegar -1 teaspoon
Soy sauce -1/2 a teaspoon
Sesame seeds -1 teaspoon,slightly crushed/powdered
Garlic -1 large pod,minced
Chili powder- 1/2 a teaspoon
Salt to taste.
Put all ingredients for the dressing in a bowl, add cucumber slices, mix.
Check the seasonings and adjust.
