A Jad - Cucumber Pickle

Slice the cucumber in four lengthwise, then slice the pieces to segments about an eighth of an inch thick.

Slice the tops of the chilies (green ones can be used if red are not available, but Thais like the color contrast), tap out any loose seeds and discard, then slice the chilies across into thin rounds.

Slice the shallots and water chestnuts.

Combine and serve. This will keep 2 or 3 weeks in a refrigerator.
