Step 1

In a large bowl, toss the shrimp with 1 teaspoon of kosher salt and let stand for 10 minutes.

Step 2

Meanwhile, in a 9- to 10-inch enameled cast-iron skillet, combine the garlic and olive oil and cook over moderately low heat, stirring occasionally, until the garlic is very fragrant and just starts to brown, 8 to 10 minutes. Add the chile and cook, stirring, until fragrant, 15 to 30 seconds.

Step 3

Add the shrimp to the skillet and cook over moderately low heat, stirring and turning the shrimp occasionally, until barely pink, about 5 minutes. Stir in the parsley, sherry, lemon zest and a generous pinch of salt. Remove from the heat and let stand until the shrimp are cooked through, 3 to 5 minutes. Serve in the skillet, passing crusty bread at the table.
