Prawn crackers, also known as prawn chips and shrimp puffs are  made from  and that serve as flavoring.Prawn crackers of premium quality are aromatic even without additives such as monosodium glutamate (MSG) and artificial prawn flavourings to enhance the smell and taste. The fried prawn crackers may be stored in airtight container for up to 3 months without preservatives and up to 9 months or so depending on the amount of preservatives added.
Most varieties of prawn crackers can also be prepared in a microwave oven, in which a few discs can be cooked in less than a minute. This will usually cause them to cook and expand in a way similar to when they are deep fried. For small quantities, this method is faster and less messy, as the crackers do not become as oily. However, this may cause the cracker to retain a stronger aroma of raw shrimp and the cracker has to be consumed within hours before it softens and loses its crispness.
