Step 1
Wash, remove shell and de-vein the prawns retaining their tails. Pat prawns thoroughly dry with an absorbent paper.
Step 2
Mix garlic paste, oyster sauce, lemon juice, soy sauce, white pepper powder, red chilli flakes and salt in a small bowl. Apply this mixture liberally on the prawns and leave aside to marinate for ten minutes, preferably in a refrigerator.
Step 3
Mix half cup refined flour, cornflour, baking powder, salt and three-fourth cup chilled water. Whisk thoroughly to make a batter of pouring consistency and set aside for fifteen to twenty minutes.
Step 4
Heat sufficient oil in a wok.
Step 5
Spread the remaining flour on a plate, add salt and mix well. Coat the prawns with the flour-salt mixture and then dip in the batter, holding by the tail. Slide them into hot oil gently and deep-fry on medium heat, turning frequently, for two to three minutes or until crisp and golden. Drain on absorbent paper.
Step 6
To make the dipping sauce, mix soy sauce, lemon juice, salt and chilli sauce well in a small bowl.
Step 7
Arrange the fried prawns on a serving plate and serve hot with the dipping sauce.
