Some like their sour flavor. Others like their crunch. Whatever the reason, pickles are a favorite of many people.

The Back Story

  • Pickles—and the process of pickling—have been around for thousands of years.
  • Why? Pickling is a way of preserving foods. Before people had refrigerators and freezers to keep foods from spoiling, they had pickling.
  • Understanding why pickling preserves foods depends on knowing a little bit of chemistry.
  • You can learn how foods are pickled and the chemistry involved by watching this video: http://www.nbclearn.com/chemistrynow/cuecard/52647
