Thinly slice the cucumbers.
For uniform slices, consider using a mandoline.
Add them to a large bowl.
Thinly slice the small white onion.
Toss the onion slices with the cucumber slices in the bowl.
In a separate bowl, mix the white vinegar, white sugar, water, and dried dill.
Stir until the sugar completely dissolves.
Pour the vinegar mixture over the cucumbers and onions.
Toss everything together to ensure an even coating.
Cover the bowl with plastic wrap and refrigerate for at least one hour.
This allows the flavors to meld together beautifully.
