PeruvianMedium · Cold
Grapefruit brings a bitterness that lime alone cannot — it lengthens the finish and gives the trout a slightly austere, very coastal character. Cayenne enters as warmth in the throat rather than fire on the tongue, and cilantro is the one element that makes all that acid feel like a complete thought rather than a sharp chord.

Method
Rinse the trout fillet under cold water and pat completely dry with paper towels. Using a sharp chef knife, slice the fillet against the grain into thin sashimi-style pieces, about 3mm thick. Arrange on a chilled plate or shallow bowl and refrigerate until ready to plate.
Cut all 4 limes in half and juice them into a bowl. Peel and supreme the grapefruit, collecting all the juice and segments in a separate bowl. Press the supreme juice through your fingers to extract every drop of citrus liquid into the lime juice.
Spoon the leche de tigre into shallow bowls or plates, pooling it generously on the bottom. Lay the sliced trout over the sauce in a single layer, letting the fish pool in the citrus liquid.
Slice the yellow-onion as thin as possible into half-moons. Scatter the raw onion over the trout and sauce for crunch and bite.

Safety & Storage
High Risk Population
Raw fish consumption poses significant risk to pregnant women, elderly individuals, young children, and immunocompromised persons. Consider cooking the trout to an internal temperature of 145°F (63°C) if serving to these groups.
Handling
Use dedicated cutting boards and utensils for raw fish. Clean and sanitize all surfaces that contact raw trout with hot soapy water followed by food-safe sanitizer.
Storage
Trout must be stored at or below 40°F (4°C) until immediately before serving. Place on ice or in coldest part of refrigerator. Do not allow to sit at room temperature for more than 15 minutes.
Shelf Life
Consume immediately after assembly. Raw fish should not be held in the danger zone (40-140°F / 4-60°C) for more than 2 hours total. Prepared dish has maximum 1-hour use window after plating.
Cross Contamination
Raw trout juice (leche de tigre) can cross-contaminate other foods. Keep raw fish and citrus sauce separate from ready-to-eat items like garnishes. Use separate serving utensils.
Cooking Temperature
No cooking occurs in this recipe. If safety is paramount, briefly sear or torch the trout slices to surface-only cook (30 seconds per side) while maintaining raw center.
Pro Tips
Technique
Slice your trout against the grain into 3mm pieces — thin enough to see light through, thick enough to feel the flesh. A dull knife crushes the cells and muddies the cure. Work fast, keep the fish cold, and trust your fingers to feel when the knife is doing the work right.
Substitution
If trout is unavailable, fresh snapper or flounder work beautifully. For a vegetarian version, substitute thick-cut tofu or daikon rounds, and increase the cayenne slightly to compensate for the missing ocean umami.
Time Saver
Make the leche de tigre up to 2 hours ahead and keep it refrigerated. The garlic and cilantro bloom better with time, and you will have more time to focus on slicing your fish with the care it deserves.
From the chef
Grapefruit brings something lime alone cannot — a bitterness that lengthens the finish and gives the trout a slightly austere, very coastal character. The leche de tigre here is looser than a ceviche cure, designed to barely set the edges while the center of each slice stays translucent and cold. Slicing the fillet against the grain into three-millimeter pieces is the whole technique; thickness is the enemy. Raw onion half-moons go on at the end for crunch and bite, cilantro makes the acid feel complete rather than just sharp, and cayenne enters as warmth in the throat rather than fire on the tongue.
