Why it Works: Perfect Pickling
Before refrigerators, food could not be stored more than a few days without bacteria or mold causing it to go bad. To get around this, several preservation methods were used. One of the most common was pickling. In its simplest form, pickling involves immersing cooked or blanched foods in a vinegar solution. The low pH (high acidity) of vinegar stops any unwanted growth. To flavor the pickles (which could include vegetables, nuts and even meat), spices, herbs and sugar were often added to the vinegar. Even though refrigerators are now available, people have grown to enjoy to the sharp, refreshing taste of pickles.
