Louisiana BBQ Shrimp

Ingredients
4 ounces (1 stick) unsalted butter, cut into small pieces
3 garlic cloves, minced (1 tablespoon)
1 tablespoon finely chopped fresh rosemary
1/4 cup fresh lemon juice (from 1 lemon), rinds reserved and sliced
1/4 cup Worcestershire sauce
1 tablespoon cream (updated version, but optional)
1 1/2 teaspoons hot sauce, such as Tabasco
1 pound (about 30) medium to large shrimp, peeled
1/2 teaspoon coarse salt
Freshly ground pepper
Directions
1. Heat a 12-inch skillet (preferably cast-iron) over medium-high heat. Season shrimp with salt and pepper. Add 1 tablespoon butter and when it is melted and foamy add the shrimp and fry until the edges are crispy and golden brown. Remove shrimp to a bowl.
2. To the same pan, add garlic, rosemary, lemon juice and rinds to pan. Stir in Worcestershire and bring to a simmer. Cook for 10 minutes. Remove the pan from the heat and strain out the solids. Return the strained sauce to the pan and add the remaining 7 tablespoons butter one at a time under low heat, stirring to incorporate until they are all melted.
3. Add shrimp back to pan and to heat through. Serve with baguette or rice.
