The cucumbers may be scored or part of the skin can be peeled for better absorption of the juice.
Layer cucumbers with the onion in a large bowl. In a separate bowl, mix remaining ingredients, stirring until sugar has dissolved.
Taste and adjust sugar for sweetness, adding more sugar, if needed. Pour over vegetables and toss lightly.
Cover and chill for 2-4 hours before serving.
