Season the shrimp with ½ teaspoon each salt and pepper. In a small bowl, stir together the garlic and lime juice; set aside. In a nonstick 12-inch skillet over medium-high, heat 1 tablespoon of oil until barely smoking. Add half the shrimp in an even layer and cook without stirring until deep golden brown, about 2 minutes. Stir, remove the pan from the heat and continue stirring, allowing the pan's residual heat to finish the cooking, until the shrimp are opaque on both sides, another 20 to 30 seconds. Transfer to a medium bowl. Repeat with 1 tablespoon of the remaining oil and the remaining the shrimp, adding them to the first batch.
