Season the shrimp with salt and pepper. In a very large skillet, heat the olive oil until shimmering. Add the shrimp and cook over moderately high heat until lightly browned, about 3 minutes. Add the garlic and cook until fragrant, about 1 minute. Add the wine and <em>sambal</em> and bring to a simmer, scraping up any browned bits on the bottom of the pan. Reduce the heat to moderately low and swirl in the butter until melted and incorporated. Remove from the heat and season with salt and pepper. Transfer to a bowl and serve with crusty bread.
