Shrimp have high levels of omega-3 fatty acids and low levels of mercury. As with other seafood, shrimp is high in calcium, iodine and protein but low in food energy. A shrimp-based meal is also a significant source of cholesterol, from 122 mg to 251 mg per 100 g of shrimp, depending on the method of preparation.  Shrimp consumption, however, is considered healthy for the circulatory system because the lack of significant levels of saturated fat in shrimp means that the high cholesterol content in shrimp actually improves the ratio of LDL to HDL cholesterol and lowers triglycerides

Many shrimp species are small as the term shrimp suggests, about 2 cm (0.79 in) long, but some shrimp exceed 25 cm (9.8 in). Larger shrimp are more likely to be targeted commercially and are often referred to as prawns.

When buying prawns there are several considerations. Firstly, see that they have all of their legs, feelers and eyes in tact and that the tail has a firm spring when curled. It should feel firm in texture and when you taste the meat it should be immediately sweet, with a long clean finish, no strong after taste.

Prawn sizing is based not only on form (HOSO or PDTO) but also on the actual number of prawns per pound or kilogram. The charts below will give you a quick and easy guide on sizing of the two forms.

Clean prawns by chopping off the tip of the head and then slitting the back including the shell to devein, but not cutting through. Wash well and apply salt, turmeric and ginger garlic paste.  Set aside to marinate.

Grind together the chillis, cloves, peppercorns, cumin seeds, garlic, onion, vinegar, salt and sugar, with a little water to a smooth paste.

Heat ½ tsp. oil in a pan and fry the ground masala on low heat till the raw smell disappears, about 1 or 2 minutes. Take off heat and cool.

Stuff the prawns with the masala paste.  Then tie with thread, roll in beaten egg and rava and shallow fry 3 to 5 minutes on each side. 

Remove the thread if you wish and serve immediately with lemon wedges and sliced onion.
