To make the marinade, whisk together the olive oil, vinegar, lime juice, lime zest, honey, garlic, cumin, chili powder, seafood seasoning, black pepper, and hot sauce in a bowl until blended. Place the tilapia in a shallow dish, and pour the marinade over the fish. Cover, and refrigerate 6 to 8 hours.
To make the dressing, combine the sour cream and adobo sauce in a bowl. Stir in the lime juice, lime zest, cumin, chili powder, seafood seasoning. Add salt, and pepper in desired amounts. Cover, and refrigerate until needed.
Preheat an outdoor grill for high heat and lightly oil grate. Set grate 4 inches from the heat.
Remove fish from marinade, drain off any excess and discard marinade. Grill fish pieces until easily flaked with a fork, turning once, about 9 minutes.
Assemble tacos by placing fish pieces in the center of tortillas with desired amounts of tomatoes, cilantro, and cabbage; drizzle with dressing. To serve, roll up tortillas around fillings, and garnish with lime wedges.
How long should delicate tilapia actually sit in an acidic marinade before the structure breaks down entirely? Acid denatures fish proteins rapidly, turning the exterior mushy if left unchecked; restrict the soak to between six and eight hours maximum for firm texture.
Oil the grill grate thoroughly with a high-smoke-point oil to prevent lean tilapia chunks from sticking and tearing during the single turn.
Keep the heat high at approximately 450 degrees Fahrenheit so the fish develops exterior char marks before overcooking internally.
Check doneness visually by testing whether the flesh opaque white and flakes apart easily with a fork at roughly nine minutes total cooking time.
Store leftover shredded cabbage and diced tomatoes separately from the assembled components to prevent excess moisture from dissolving the tortillas by day two.
Repurpose remaining grilled fish chunks and chipotle-lime dressing into a cold grain bowl or packed lunch wrap within forty-eight hours for food safety and optimal texture.
Chilling the chipotle sour cream base for at least two hours allows the capsaicin from the adobo sauce to evenly distribute through the dairy fats. Proper resting ensures every bite balances spicy heat with bright citrus notes.
