Tips for Buying PrawnsWhen purchasing prawns, you have a choice of buying them fresh or frozen. Both will work just as well in cooking, but frozen prawn will have to take time to defrost and are not be as flavorful as fresh prawn once cooked. They also tend to be tougher after cooking, so when you can, fresh prawns are the way to go.
Cooking PrawnsPrawns can be cooked in a variety of ways, just as you would with other types of seafood. They can be grilled, broiled, fried, or steamed and can be cooked with the shell on or off. Prawns can also be cooked with the vein in or de-veined. Most people will remove the vein before cooking for personal reasons, but also because the taste can be gritty when bitten into.
If cooking with frozen prawn, it is important to make sure that they are completely defrosted. This can be done easily by placing the prawn in a waterproof package or wrapping in plastic wrap, and placing in cold water for about an hour. Once defrosted, prawn are ready to cook and should be used immediately.
Shell On or Off?Deciding on whether to cook with the head and shell on or without is a personal decision. If you choose to cook without the shell, you will find it is a little easier to remove if the prawn is still slightly frozen. First remove the head by twisting it off. Next remove the legs, then, holding the prawn by its tail, pull the shell from the body. At this point you can choose to de-vein the prawn. This is done by taking a thin, sharp knife and running it along the vein. Run the prawn under cold water and the vein should wash away.
When cooking prawn, one thing to remember is that they cook fast. If using prawn in a stir fry dish, wait until the last minute to add prawn as they will cook in as little as 30 seconds. Other methods, such as breading and frying, prawn can cook in under a minute.
