Why it works: Shrimp and lettuce work together. They rank in the top 10% of all ingredient pairs, and 426 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓
The recipe
Serves 6Ingredients
Contains: wheat, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Preheat the grill to medium-high heat, about 450°F (232°C).
Grill the peeled and deveined shrimp in a single layer for 2 to 3 minutes per side, until opaque and flesh flakes, reaching 145°F (63°C) in the thickest part.
Warm the tortillas on the grill for 20 to 30 seconds per side, or until pliable and lightly marked.
If the lettuce is not already shredded, shred it finely and set it aside.
Divide the grilled shrimp among the warm tortillas.
Top each taco with shredded lettuce and pico de gallo, then serve right away.
