3 med. slender cucumbers
1 sm. onion
1/2 c. sugar
1/2 c. white vinegar
1/4 c. water

Peel and thinly slice cucumbers and onions. Layer in a bowl, salting each layer generously. Cover with cold water and ice cubes; let sit for 15 minutes. While this sits, make brine of sugar, vinegar, and water, stirring (or heat slightly, if you prefer) until sugar dissolves. Drain and thoroughly rinse cucumbers and onions, squeezing them as you rinse. Add to brine and chill.
