Transport your palate to the tropics with this sophisticated twist on a coastal classic. This recipe balances the bright acidity of lime with the velvety richness of coconut milk, elevated by the buttery crunch of toasted macadamia nuts. Served alongside homemade salty plantain crisps, it is the ultimate refreshing appetizer for any season.

Ingredients

For the Coconut Lime Ceviche

• 1 lb Sushi-Grade White Fish: Sea bass, mahi-mahi, or snapper, cut into 1/2-inch cubes.
• 1/2 cup Fresh Lime Juice: Approximately 4–5 large limes.
• 1/2 cup Full-Fat Coconut Milk: Unsweetened and well-shaken.
• 1 small Red Onion: Very thinly sliced (julienned).
• 1 Fresno Chili or Jalapeño: Deseeded and finely minced.
• 1/4 cup Fresh Cilantro: Roughly chopped.
• 1/2 tsp Sea Salt: Plus more to taste.
• 1/2 cup Diced Mango: Optional, for a hit of sweetness.

For the Toasted Macadamias & Crisps

• 1/2 cup Macadamia Nuts: Raw, roughly chopped.
• 2 Green Plantains: Unripe (peel should be entirely green).
• High-Heat Oil: Coconut or avocado oil for frying.
• Fine Sea Salt: For seasoning the crisps.

Step-by-Step Instructions

1. Prepare the Plantain Crisps

Peel the green plantains and slice them into paper-thin rounds using a mandoline. Heat 1 inch of oil in a heavy skillet to 350°F (175°C). Fry the slices in small batches for 2–3 minutes until golden and rigid. Drain on paper towels and sprinkle immediately with sea salt.

2. Toast the Macadamia Nuts

Place chopped macadamia nuts in a dry skillet over medium heat. Shake the pan frequently for 3–5 minutes until the nuts are fragrant and light golden brown. Remove from heat immediately to prevent scorching and set aside.

3. “Cook” the Fish

In a glass or ceramic bowl (avoid metal), toss the cubed fish with the fresh lime juice and red onion. Ensure the fish is fully submerged. Cover and refrigerate for 15–20 minutes. The fish is ready when the exterior turns opaque but the center remains slightly tender.

4. Combine and Infuse

Drain about half of the lime juice from the bowl. Stir in the coconut milk, minced chili, cilantro, and mango (if using). Season with 1/2 teaspoon of sea salt. Let the flavors meld in the refrigerator for another 5–10 minutes.

5. Garnish and Serve

Divide the ceviche into chilled bowls. Top generously with the toasted macadamia nuts for a buttery crunch. Serve immediately with a side of plantain crisps.

Fact-Check: The Science of Ceviche

Does lime juice actually “cook” the fish?
Technically, no. Heat cooking uses thermal energy to vibrate molecules and denature proteins. Ceviche uses acidic denaturation. The citric acid from the lime juice changes the protein structure of the fish, turning it firm and opaque, but it does not kill parasites or bacteria as effectively as heat. This is why using “sushi-grade” fish—which has been flash-frozen to specific temperatures to eliminate parasites—is essential for safety.
