Ingredients
  

The Citrus Marinade
  • 2 sea bass fillets 6 to 8 ounces each
  • 1 blood orange juiced (approx. 1/3 cup)
  • 4 large garlic cloves minced
  • 1/4 cup olive oil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon coarse black pepper
The Lipid Crema
  • 1/4 cup mayonnaise
  • 1/4 cup sour cream
  • 1/4 cup prepared salsa
  • 1 tablespoon fresh lime juice
  • 2 to 4 dashes hot pepper sauce
The Grilled Architecture
  • 1 avocado halved and pitted
  • 1 tomato halved
  • 1/2 head romaine lettuce
  • 2 jalapeno peppers halved and seeded
  • 2 green onions
  • 2 flour tortillas 8 or 10-inch
  • 2 tablespoons fresh cilantro chopped

Method
 

The Marinade and Protein Preparation
  1. Place the sea bass fillets in a shallow vessel. Whisk together the blood orange juice, minced garlic, and olive oil, then pour over the protein.
  2. Season with salt and pepper. Turn the fillets to ensure complete saturation and allow for a 15 to 20-minute osmotic transition.
The Crema Emulsion
  1. In a small bowl, whisk together the mayonnaise, sour cream, salsa, lime juice, and hot pepper sauce until a stable, smooth emulsion is formed.
  2. Season with salt and pepper to taste and set aside.
The Thermal Char and Vegetable Prep
  1. Heat a heavy cast-iron grill pan over medium-high heat and apply a light coating of olive oil.
  2. Place the avocado, tomato, romaine, jalapenos, and green onions cut-side down on the pan.
  3. Execute a rapid char until distinct architectural marks appear, then transfer to a cutting board to chop into uniform components.
The Protein Execution
  1. Place the sea bass fillets flesh-side down on the hot grill pan.
  2. Grill for approximately 4 minutes per side (based on an 8-minute-per-inch rule) until the exterior is charred and the interior reaches a medium-rare state.
  3. Transfer the fish to the cutting board and divide into large, structural chunks.
Final Assembly
  1. Briefly grill the tortillas for several seconds per side until warm and pliable.
  2. Layer the charred chopped lettuce onto the tortillas, followed by the sea bass, tomato, avocado, and jalapenos.
  3. Apply a generous volume of the lipid crema and garnish with fresh cilantro and a final squeeze of lime.
