Carefully shell and de vein the prawns so that the tail is intact . Make 2 to 3 small cuts on the sides of the prawn to make it straight. This is an important step because even after its deep fried, the tempuras will remains straight.
Mix the flours with little water( preferably icy cold water to make thick and lumpy paste and add garlic mince, cayenne powder and salt to taste.
Dip the prawn at a time and coat it with well with bread crumbs. Arrange them in a plate. At this time you can choose to freeze them. Simply cling wrap the plate and pop them into the freezer. But if you want to go ahead and make them soon , refrigerate them for alt least 30 minutes
Heat oil to a medium fire and and deep fry until it is golden brown .
Drain in a absorbent paper and serve with the dipping sauce. Well I serve it with tomato ketchup.
