A quick and easy 5-minute summer side dish featuring crisp cucumbers and sharp onions marinated in a tangy, slightly sweet vinegar dressing with fresh dill.
Soak sliced onions in cold water for 10 minutes before mixing to mellow sharpness. Use a mandoline slicer for even thin slices to help marinade absorption. Marinate at least 30 minutes for best flavor; up to 24 hours is possible but cucumbers soften more. Adjust sugar and vinegar to taste. Optional additions include jalapeño slices, celery seed, or swapping herbs like mint or basil.
