For the Dressing
White Vinegar or Cider Vinegar The tangy base for the dressing; cider vinegar adds a subtly sweeter profile.
Vegetable Oil or Light Olive Oil Balances the dressing s acidity; using light olive oil makes it a healthier option.

How to Make Cucumber Onion Salad
Wash and Slice: Start by washing the cucumbers thoroughly. You can choose to peel them or leave the skins on. Thinly slice the cucumbers and sweet onion using a knife or mandoline for even cuts. Aim for about 1/4-inch slices for the best texture.
Whisk the Dressing: In a large bowl, combine the vinegar, oil, water (if using), and sugar. Whisk them together until the sugar dissolves completely, creating a tangy dressing that will energize the salad.
Toss Ingredients: Add the sliced cucumbers and onions to the dressing. Gently toss everything together, ensuring each piece is well-coated in that delicious, zesty mix. This is where the magic begins!
Refrigerate: Cover the bowl and refrigerate the salad for at least 1 hour, though 4 hours will deepen the flavors beautifully. Give it a stir every so often to keep everything evenly dressed and fresh.
Add Dill and Season: Just before serving, toss in the chopped fresh dill and season with salt and pepper to taste. This finishing touch brightens the salad and brings out the best flavors.
Optional: Serve with a sprinkle of crumbled feta for an extra burst of flavor.
