Persian cucumbers are slender, seedless or low-seed cucumbers with smooth, thin skin and a mild, slightly sweet flavor. Use them sliced in salads, as a crunchy snack with dips, or thinly sliced in sandwiches and wraps. Store unwashed in the refrigerator crisper drawer to maintain firmness; consume within a week for best quality. They also work well for quick pickles and add hydration to summer dishes.
