What is a pickle? A pickle, at its most broad and basic, is just a vegetable that has been made sour. Pickling refers to the act of souring (or acidifying) something (usually vegetables, but sometimes fruits, eggs and even meats).
Sour cream is a dairy product obtained by fermenting a regular cream with certain kinds of lactic acid bacteria. The bacterial culture, which is introduced either deliberately or naturally, sours and thickens the cream. Its name stems from the production of lactic acid by bacterial fermentation, which is called souring. The taste of sour cream is only mildly sour.
