Clean your shrimp before preparing them by washing them in running water and removing their heads. Remove the veins by cutting 1/8 inch around the exterior of the shrimp, from the tail up to above the head. Get rid of the vein of poop. Keep the shells in place as well as dry them on paper towels.
Mix the cornstarch, flour cayenne powder, paprika and salt in a bowl. Make sure that each shrimp is thoroughly coated, including the slit you cut.
Set it on an aluminum rack and place it aside until you're ready to cook.
In a pan set on medium heat, cook to the butter, stirring until it begins melting, then you can add garlic.
Let the garlic cook until it is crisp and golden, which takes about 3 minutes. This is what garlic will look once it's cooked. The garlic butter should be transferred into another bowl.
Then, in the pan you used to cook them place an olive oil to cook shrimp and allow them to become they are crispy all sides around an hour per side. Or until the meat is opaque.
The garlic butter should be added back in the pan together with the shrimp. Cook for another 1-2 mins so that the flavors can mix. Sprinkle the lemon juice on the top of the dish and test the taste.
Serve with white rice, lemon wedges and Hawaiian Mac Salad.
