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).
Save. Sour salt is crystallized citric acid, a weak acid derived from citrus fruits such as lemons and limes. Sour salt is used as a seasoning to add a soft pucker to lemonade, borscht and other recipes. It also is used in canning and helps preserve foods such as apples and pears, which otherwise darken or soften.
