Both sets of my grandparents are Cantonese, so I grow up eating plenty of Chinese Cantonese dishes. For special occasions, we always have at least one seafood dish, and one of the most requested dish is this Cantonese dry fry prawns, a.k.a. Har Lok (干煎虾碌). This is such a quick and easy prawns dish to prepare, and the sweet and sour sauce is always a hit.
Sweet and sour sauce for har lok (Cantonese dry fry prawns)
The sweet and sour sauce is very simple and using staple pantry sauces. You will need:
Choosing the correct prawns size to use
Depending on the occasions, you can use either jumbo size prawns, or medium size prawns for this dish:
- For really special occasions, like Chinese New Year, it is best to use the biggest size prawns you can get. My Mom always get jumbo size prawns for Chinese New Year, which is about 15-25 prawns per kilogram.
- For everyday occasions, it is okay to use medium size prawns (which is what I use in the photos), and it should be about 40-50 prawns per kilogram.
How to cook prawns so they stay crunchy
The biggest sin one can commit when preparing prawns/shrimps is overcooking. Anytime you cook prawns/shrimps, it is always best to undercook rather than overcook. Perfectly cooked prawns/shrimps will have crunchy texture, while overcooked ones will have chewy leathery texture, which is a big no no.
To prepare the perfect har lok, here are my tips:
- When you fry the prawns in oil, be extra sure that the moment you see them turn orange, you should immediately remove from heat and transfer them to a plate.
- When you return the fried shrimps to the pan to mix with the sauce, be sure to do this quickly. You should only need at most 30 seconds to toss the shrimps with the sauce. If for any reason you need more time than this, it is better to turn off the heat once the sauce boils, remove the pan/wok from heat source, then add the fried shrimps and toss.
I hope my recipe will lead you to perfectly crispy and crunchy prawns with delicious sweet and sour sauce.
