Prawn pickle is the preserved food item through either anaerobic fermentation in brine or immersion in vinegar. The pH of fish pickle should be 4.6 or lower to reduce the microbial activity. Traditionally, spicy, pungent pickle made of vegetables like lime, gooseberry, ginger, garlic etc. were used as an important side dish along with meals and used to be considered an appetizer. Though such pickles made of fish or meat was practically unknown in the past, such products have now become very popular and products under several brand names are now available in the market.
