Shrimp is doused with pastis, a sweet, licorice-flavored French liqueur, and ignited in this showstopping recipe from La Petite Maison chef Alain Allegretti.
Preheat oven to 375.
Heat oil in a large ovenproof skillet over high heat. Add shrimp and cook, turning once, until seared on both sides. Transfer to oven and continue cooking until shrimp is opaque, about 3 minutes.
Add pastis to skillet and carefully return to high heat; ignite to flambe. Let cook until flame dies out. Remove shrimp from skillet and set aside.
Drain fat from skillet and add butter and chicken stock. Cook over medium-high heat, whisking to emulsify. Cook until reduced by half, about 1 minute.
Return shrimp to skillet and cook until heated through. Place two shrimp on each of 4 serving plates and drizzle butter mixture around shrimp on plates; season with fleur de sel and pepper and serve immediately.
