Pro-Tips for the Best Cucumber Onion Salad

• Slice Ultra-Thin: Use a mandoline slicer to achieve paper-thin cucumber and onion slices. Thin slices absorb the vinegar marinade much faster and hold more flavor.
• Salt & Drain for Maximum Crunch: Toss cucumber slices with 1 teaspoon of salt and let them sit in a colander for 10–15 minutes before adding the vinegar. Pat dry to remove excess water so your marinade doesn’t get watered down.
• Chill Before Serving: While you can eat these salads immediately, letting them marinate in the fridge for at least 30 minutes makes the vegetables extra crisp and cold.
