Pickled Cucumber is a known ingredient all around the world and like many other kinds of pickle is popular among Iranians, as a side dish or an ingredient in some foods like Olivieh Salad.
Persian cucumbers have qualities that set them apart from the common garden cucumber in three ways: their skin is smooth and thin, flesh is very crisp, sweet and they are void of developed seeds. Persian cucumber measures 4 to 6 inches in length, as this is the size when it is at its peak of sweetness.
Although Persian cucumbers enjoy the classification as a burpless variety, their culinary utilities are much more versatile, as they can be treated as a slicer and even a pickling cucumber out of both choice and necessity. Thus, you can use Persian cucumbers in a multitude of applications to provide both textural and flavor qualities. Persian cucumbers can absorb other flavors quite quickly, which gives them the opportunity to act as a vehicle for spices in a short period of time.
Consider using Persian cucumbers as a salad ingredient, for salsas and creamy dressings. They are a great cooling ingredient in hot dishes, make a perfect accoutrement to roasted fish and lamb, pair well with mint, chiles, mustard, cumin, citrus and fresh cheeses, such as chevre, feta and cotija.
( A pickled cucumber is a cucumber that has been pickled in a brine, vinegar, or other solution and left to ferment for a period of time, by either immersing the cucumbers in an acidic solution or through souring by lacto-fermentation. Wikipedia )
