Tomato and Avocado Ceviche

You can use almost any whitefish in this recipe, though we've had very good success with halibut. Other fish suggestd include tuna, salmon, sea bass, sole, sea scallop and shrimp. The recipe suggests thin fish such as sole, flounder or tilapia as easy because they do not need to be cut width-wise (which should be no thicker than 1/3 inch for even cooking). The important part is to keep the pieces of fish approximately the same size cubes so that they cook in the citrus at the same rate. Because we are essentially cooking the fish with the acid from the citrus and not applying any heat, it's important to use fresh (from the store that day, not frozen, etc) fish and fresh lemons and limes. The brightness of the lemons and limes are the key to the flavor of the dish. Don't worry, it cooks, and will turn opaque to prove it. You actually can overcook things with citrus, so don't leave it in the marinade too long.

Be sure to pat all seafood dry with paper towels so that any moisture does not water down the marinade. To prep in advance, you can mix all the citrus marinade ingredients together (jalepeno, red pepper, garlic, lemon, lime, etc.) in one bowl, the cut seafood in another, and the added veggies minus avocado (scallions, cilantro, cherry tomatoes, oil, and sugar) in another. When it is time to start marinating, add the fish to the citrus. Add the avocado just before serving to prevent it from breaking down, turning brown, or making everything green. This will serve a generous 4 portions for a first course or a smaller 6 portions.

1teaspoon grated lime zest from 1 lime

1/2cup juice from 4 limes

1/2cup juice from 4 lemons

1small red bell pepper , stemmed, seeded, and chopped fine

1-2 jalapeno chile (small), stemmed, seeded, and minced

1 medium garlic clove , minced or pressed through a garlic press

1cup cherry tomatoes , quartered

3tablespoons minced fresh cilantro leaves

1/2teaspoon sugar

1 ripe avocado , pitted and diced fine

Instructions

1. If using shrimp, peel them completely, devein, and slice each shrimp in half lengthwise using a paring knife (through the deveined groove in the back). If using scallops, remove the side tendon and slice into 1/3-inch-thick rounds. If using fish, remove any bones and slice into 1-inch squares about 1/3 inch thick.

2. Stir the lime zest, lime juice, lemon juice, bell pepper, jalapeno, garlic, and 1/2 teaspoon salt together in a medium bowl. Gently stir in the seafood, cover with plastic wrap, and refrigerate until the seafood is firm, opaque, and appears cooked, 45 to 60 minutes, stirring halfway through the marinating time.

3. Place the mixture in a fine-mesh strainer, leaving it a little wet, then return to the bowl. Gently stir in the oil, scallions, tomatoes, cilantro, and sugar followed by the avocado. Season with salt and pepper to taste before serving.
