Veggies that can be pickled include cucumber (cuke) and BEET (BEET). Pickling is a process of preserving food by soaking it in a brine solution, usually vinegar or salt water. Pickling has been used for centuries to preserve food and add flavor. Cucumbers and beets are two vegetables that are commonly pickled. Cucumbers are usually sliced and soaked in a vinegar-based brine, while beets are boiled and then soaked in a vinegar-based brine. Pickled cucumbers and beets are often served as side dishes or used as ingredients in salads and other dishes.
