How to Devein Tiger Prawns
Tiger prawns have grey-striped shells and can be deveined with the shell on or off. (Hemera Technologies/ Images)

The tiger prawn -- Penaeus monodon -- is characterised by its large size and grey-striped shell, which turns pinkish-orange when cooked. This type of succulent shrimp is raised in tropical habitats from India and Thailand to Australia and South Africa. It is served throughout the U.S., breaded, sautéed or cooked and chilled with a side of cocktail sauce for dipping. The tiger prawn's digestive tract -- also called a vein -- runs down its back. It's black, and while edible, can be removed before cooking. This process is called deveining.

    Run the tip of a paring knife down the back of the black vein on the prawn, from top to bottom, slicing about 1/8-inch deep into the flesh.

    Grasp the tiger prawn in the middle, with the curved back of the prawn facing up.

    Run the tip of a paring knife, lengthwise, down the middle of the shell, piercing the shell deep enough to cut through the shell and into the prawn's flesh.
