Tomato Ketchup Prawns
Originally uploaded by Food Trails.Prawns are sweet and have an enticing flavour. Undoubtedly, they are one of my favourite ingredients. They may be caught in salt water and fresh water and they are being farmed too.
There are prawn farms in Singapore. One such high-tech marine prawn farm is located at the sea front on Pulau Ubin. This farm produces both black tiger prawns and white prawns all year round. Due to intensive cultivation, black tiger prawns are harvested every 120 days at the farm. Annually there are two and a half cycles.
Usually prawns caught from salt water are more expensive. Although shelled prawns or shrimps are available from chiller or freezer of the supermarkets. I prefer to buy them fresh and raw from the wet market because more flavour is retained. When using prawns in your dishes, overcooking should be avoided as this makes the prawns tough. To avoid this, it is always better to sauté the prawns till just cooked and then set aside. Add them back to the dish at the last stage of cooking.
When purchasing prawns, look for glossy, undamaged shells, legs and tails, plump and shinny black eyes. They should be no signs of dark or discolouration. Refrigerate as soon as after purchase. For convenience, divide into quantities required for each meal or recipe and keep them in plastic bags before freezing.
Before cooking prawns, whether they are used with shells intact or shelled, remember to remove the intestinal veins. Prawns shells are segmented just bend the shells to expose the joint, make a small incision in each prawn’s back and carefully draw out the dark vein. A toothpick is a handy tool here. When recipes call for prawns to be shelled, retain the last segment of shell and the tail fins to give a more decorative appearance to the finished dish, as shown here in the picture.
Shells and heads of prawns make good stock. To obtain this, fry them in a little oil on high heat, add just enough of hot water to cover, and boil for 15 minutes. Strain, discard shells and freeze the stock if not immediately required. . This type of stock is used in our local fare, prawn noodle soup.
