1 c. sugar
1/2 c. water
1/4 c. cider vinegar

Boil together until sugar is dissolved. Cool. Peel 2 cucumbers and slice real thin. Put salt on cucumbers and let set a while about 10 minutes. Squeeze dry, and mix with sliced red onion. Pour cooled liquid over onion and cucumbers. Chill, best if made a day ahead.
