Tips for the Best Marinated Cucumber Salad

• Use fresh, firm produce: This helps maintain a nice crunch and visual appeal.

• Chill for at least an hour: Letting it marinate allows the flavors to develop fully.

• Thin slices absorb more flavor: A sharp knife or mandoline makes this easier.

• Adjust to taste: Add a pinch of sugar if the vinegar is too sharp, or throw in chili flakes if you prefer a little heat.
