Set broiler to low and heat the oven.

In a small bowl, crush the garlic and mix with the salt. Mix in cayenne and paprika. Stir in oil and juice to form a paste.

In a large bowl, toss the shrimp in the paste until evenly coated.

Skewer the shrimp, and place on a foil-lined baking sheet. Cook 4" from the broiler for 4-5 mins. Flip and cook another 4-5 mins. Serve.
