Add corn starch, garlic powder, paprika, red chili powder, and season with salt and pepper in a large bowl.
Coat the clean and devein prawns in the corn starch mixture and dust off any excess corn starch.
Next, add around 1 inch of oil to a pan, and turn the heat to medium-high. Once the oil is hot, pan-fry the prawns for 1-2 minutes on each side.
In a separate pan, add butter and garlic. Turn the heat to medium and saute for 2-3 minutes or until fragrant. Optional - season with salt if your butter is not salted.
Squeeze in lemon juice and white wine, and add back in the prawns.
Saute on high heat for 1 minute.
