De-vein the prawns and peel the shells off.
Chop the garlic and keep it aside. Crush the chilies to flakes.
In a thick-bottomed pan, melt butter and add 2 tablespoons of olive oil.
Once the oil is hot, fry the garlic and chili flakes.
Wait for the garlic to turn golden brown, place the prawns on the pan, and give the pan a quick shake.
If required sprinkle some salt.
Fry the prawns for less than 3 minutes on each side, and switch off the flame. For bigger prawns cooking time could increase.
Take the fried prawns and place them in a bowl.
Add a tablespoon olive oil to the left over mixture in the pan, and mix well.
Drizzle this mixture on top of the fried prawns, squeeze a lime wedge. Serve fresh and hot.
