Pickles are a type of food made by preserving vegetables, most commonly cucumbers, in a brine or vinegar solution. This process gives them a tangy, acidic flavour and a crisp, crunchy texture. Pickles come in a variety of shapes and sizes, from whole baby pickles to sliced dills. They're enjoyed on their own as a snack, but also add a burst of flavour to sandwiches, burgers, and salads.
