This is fried big prawns or ha look in Cantonese.
My father used to to cook a few dishes very well. One of them is this ha look. The shells of the prawns became golden-brown, crispy and aromatic while the flesh remained sweet and succulent. Unfortunately I did not watch him do this. Before he passed away, he didn't pass on the recipe or skills to us. If not I could sell them to make some money, not a fortune, maybe $200. If 100 of my blog readers or Facebook-friends buy it, I could get $20,000 already!
Haha, just day-dreaming!
