Directions

1. Pat shrimp dry, and place in a medium bowl. Add lemon peel strips, oil, limoncello, rosemary, 1/4 teaspoon pepper, and 1/4 teaspoon salt. Toss to coat. Cover and marinate in refrigerator at least 30 minutes or up to 1 hour.
2. Meanwhile, remove outer stalks of celery, and reserve for another use. Finely chop inner celery stalks and heart to yield 1 cup; set aside. Pick off tender yellow leaves to yield about 1/4 cup; set aside for garnish. Reserve any remaining celery stalks for another use.
3. Heat butter in a large skillet over medium until foamy. Add chopped celery, garlic, remaining 1/2 teaspoon pepper, and remaining 1/4 teaspoon salt; cook, stirring often, until mixture is fragrant, 30 seconds to 1 minute. Add shrimp, reserving marinade in bowl; cook, flipping shrimp occasionally, until shrimp begin to turn pink, about 1 minute. Add whiskey, lemon juice, and reserved marinade in bowl; cook, stirring occasionally, until sauce bubbles and shrimp turn opaque, 1 to 2 minutes. Remove from heat, and sprinkle with celery leaves. Serve immediately with lemon wedges and toasted baguette.
