What does pickling mean?
Pickling is the process of preserving food by immersing it in a seasoned brine, vinegar, or similar acidic solution. The technique is especially associated with vegetables such as cucumbers, carrots, onions, and peppers, which become crunchy and acquire a sharp, salty, or sour flavor. The term also has a technical industrial meaning: pickling is the treatment of metal with acid to remove surface oxides, scale, or other impurities, often as preparation for painting, plating, or further processing. In general use, pickling usually describes food preservation, while its industrial sense is familiar in manufacturing and metalworking. The word is useful because it connects an everyday culinary practice with a specialized chemical process whose basic principle—using an acidic solution to alter and preserve a material—is closely related.
