Lemon and orange liven up these garlicky shrimp, made spicy with a bit of red pepper flakes. Add more pepper flakes to your liking or sprinkle the marinade mixture with a few drops of hot sauce or pepper oil, if you dare! This recipe becomes Phase 1 if you use lime zest and juice instead of that of an orange.

Makes 10 (3-piece) Servings
Prep Time: 15 minutes
Marinating Time: 30 minutes or overnight
Cook Time: 10 minutes

Cut the zest from the whole lemon, then peel and chop half of the fruit. Cut the zest from half of the orange, then peel and chop half of the fruit. Place lemon and orange zests and chopped fruits in a medium bowl. Add oil, garlic, black pepper, and pepper flakes; stir to combine. Add shrimp and toss to coat well. Cover and marinate for 30 minutes at room temperature or overnight in the refrigerator.

Heat a grill or grill pan over medium-high heat.

Remove shrimp from marinade, allowing bits of citrus to stick. Discard marinade. Season shrimp lightly with salt; grill until shrimp is opaque and cooked through, about 3 minutes per side. Squeeze a little fresh lemon or orange juice (or a combination of both) from the remaining fruit halves over the shrimp just before serving. Serve warm or at room temperature.

Make-Ahead: Shrimp can be marinated up to 1 day in advance and grilled up to 6 hours ahead. Refrigerate grilled shrimp until ready to use; bring to room temperature before serving.
