Take prawns, milk, lemon juice, paprika, garlic powder, salt, pepper powder in a bowl and mix well. Cover and leave it to marinate for 2 hours in fridge.

Mix together the sauce ingredients in a bowl. Taste and adjust the sauces. Set aside till use.

Heat oil for deep frying. Take cornstarch in a bowl. Remove the prawns from the marination using tongs and drop it directly into the cornstarch. Coat it really well in the cornstarch.

Now drop this into the hot oil and fry till golden brown and crispy. It will take around 3 to 5 minutes. Remove from the oil using a slotted spoon and take it in a bowl.

Pour the prepared bang bang sauce over the fried prawns and toss to combine. Spoon this over a bed of shredded lettuce, sprinkle top with spring onions. Serve hot.
