Preparation / Directions:
Did some rummaging around in my cookbooks and came up with the following. This first one sounds like it's on the track of the cucumber pickles you had at the Chinese place, though these are diced, not sliced and call for sesame oil rather than seeds.
Peel the cucumber and cut into small dice. Sprinkle with remaining ingredients and leave for 5 minutes before serving. Make sure sugar has dissolved before serving.
