Prawns

In many parts of South Africa, small and medium shrimp are sold simply as shrimp, while large, extra-large, and jumbo shrimp are called prawns. Unfortunately, this ‘rule’ doesn’t always hold. In some areas, all shrimp, small and large, are sold as shrimp, while in other regions, all you’ll find are prawns. Medium-sized shrimps are called shrimps in the US, but prawns just about everywhere else.

Shrimps are slightly more tender and delicate in flavour than prawns and are usually used as a garnish or in hors d’oeuvres. The delectable deep-sea prawns, generally served as a main course, should not be confused with the estuarine mud prawns, which are edible but can be unpleasantly gritty. Once considered a luxury item, prawns and shrimps are becoming more popular for dinner parties because they are relatively inexpensive compared with the increasingly high cost of beef or lamb. Like all shellfish, they are low in kilojoules.

Prawns are found in a wide range of species and colours, and all have firm, sweet flesh. Medium-sized prawns are what’s on most seafood menus, especially in prawn cocktails, speared as kebabs, deep-fried or baked in sauce. You’ll get anything from 25 to 50 prawns in a 500 gram bag or box, depending on their size. But you’ll only get about 10 jumbo prawns, per 500 grams, and that depends on whether the heads are included. The bigger the prawn, the more ‘special’ the character, ie, less delicate and sometimes even with a distinct salty tang. Tiger prawns, brown with dark branding, are as big as you’ll get in this shellfish category. They’re a favourite on the barbecue or buffet table and commercial farming has seen fishmongers well-stocked with this warm saltwater favourite.

Where to Buy

Canned and frozen shrimps and prawns are freely available in most supermarkets. Fresh ones are difficult to come by because the catch is almost always frozen at sea. Frozen shrimps are usually cooked, deveined and shelled although some shops stock whole uncooked shrimps. Frozen prawns come with or without the head and in the shell, or deveined and shelled. Whole frozen prawns are slightly cheaper than the other varieties. Although in South Africa we trawl our own deep-sea prawns off the KwaZulu-Natal coast, much of what is available is imported from Australia, Taiwan and Mocambique. Tiger prawns, with characteristic dark stripes, originate from Taiwan. Prawns vary considerably in size from the smaller queen prawns to the larger king and jumbo prawns. Budget for 100 grams of prawns per person for an average serving.

Handling Frozen Shrimps and Prawns

Frozen shrimps and prawns should be thawed completely for the best results. If they are frozen in a solid block of ice, remove from the freezer the night before. Leave in the bottom of the refrigerator until ready to use. Individually blast frozen prawns or shrimps (loose in a packet like frozen vegetables) need only 20-30 minutes to thaw at room temperature. If you are in a hurry, place the sealed plastic bag of frozen seafood in a bowl of warm water. It will then defrost in minutes. Raw prawns and shrimps have a glossy opaque appearance. If the outside flesh is pinkish, they are already cooked.

Cooking Shrimps and Prawns

1. Place thawed raw shrimps and prawns in boiling salted water to cover, bring back to the boil, and watch cooking time carefully from that point. Simmer for 1 to 2 minutes, then drain. Shell and devein, if necessary, according to the directions given below.

2. Prawns can also be fried or grilled.

3. Canned shrimps and prawns are already cooked. Take care not to overcook as they will taste rubbery. Drain liquid and use as is, or heat through gently if using in a hot dish.

How to Devein and Shell Prawns

Note: Deveining and shelling prawns are fiddly time-consuming tasks. Although slightly more expensive, buy them ready processed for convenience unless you particularly wish to cook in the shell.

1. Pull off the tail shell

2. Twist off the head

3. Peel off body shell.

How to devein prawns leaving shells on.

1. With a pair of scissors slit open the back of the shell starting at the head end. If the head is attached, use a sharp knife to slit from head to tail.

2. Insert a toothpick beneath the vein until you have dislodged it.

3. Pull out the rest of the vein with your fingers.
