Sea Bass and Tomato Ceviche

This elegant sea bass and tomato ceviche is a vibrant, zesty dish that celebrates the freshness of high-quality seafood. By curing delicate white fish in a piquant 'leche de tigre' made from lime, ginger, and aromatics, you create a sophisticated starter bursting with bright, clean flavours. The addition of colourful heirloom tomatoes provides a juicy sweetness that perfectly balances the subtle heat of the habanero and the acidity of the citrus marinade.

As a diabetes-friendly recipe, this dish is naturally low in carbohydrates and rich in lean protein. It is an excellent choice for a light lunch or an impressive dinner party appetiser that feels indulgent while remaining heart-healthy. Serve it immediately in chilled bowls to ensure the fish maintains its perfect texture and refreshing temperature.

How to make Sea Bass and Tomato Ceviche

Purée chopped onion, celery, garlic, habanero, ginger, sugar, 1 tablespoon salt, and 60ml water in a blender until smooth. Transfer to a small bowl; stir in coriander. Cover and chill 1 hour.

Meanwhile, trim fish to create clean edges. Holding your knife at a 45° angle, slice into 1/4"-thick pieces; try for one fluid movement per slice to avoid shredding flesh. Transfer to a plate as you go, separating layers with sheets of plastic wrap as needed. Chill until ready to serve.

Strain purée through a fine-mesh sieve into a small bowl, pressing down on solids to extract as much liquid as possible (you should have about 120ml ; this is your "leche de tigre"). Stir in passion fruit juice and lime juice, adding a bit more lime juice to balance acidity if needed.

Arrange fish and tomatoes in shallow bowls; spoon leche de tigre over. Season with salt and top with sliced onion and microgreens. Serve immediately.
