Kerala Pickles – Pickle is the oldest and most successful method of food preservation. The history of pickle making stretches back to 2030 B.C. The pickles in South Asia are homemade and every district, village and family have its own formula closely guarded and handed over from mothers to the daughters. Women from different regions prepared pickles differently. It is important to document them since each region has its own way of using spices and preparing them in a different way.
