What is "gherkin"?

Gherkins are a type of small, firm cucumber that are typically pickled in vinegar and spices. They are often used as a condiment or garnish in sandwiches, burgers, and salads, and can also be enjoyed on their own as a snack. Gherkins are low in calories and high in fiber, making them a healthy addition to meals and snacks. They have a tangy and slightly sour flavor that is characteristic of pickled foods, and are often combined with other ingredients to create a sweet and sour flavor profile. Gherkins have been enjoyed for centuries and are a popular food item in many different cultures around the world.
