Serves 6 as an appetizer

Serve shrimp with crusty bread for dipping in the richly flavored olive oil. The dish can be served directly from the skillet (make sure to use a trivet) or, for a sizzling effect, transferred to an 8-inch cast-iron skillet that’s been heated for 2 minutes over medium-high heat. We prefer the slightly sweet flavor of dried chiles in this recipe, but 1/4 teaspoon sweet paprika can be substituted. If sherry vinegar is unavailable, use 2 teaspoons dry sherry and 1 teaspoon white vinegar.
