This authentic Peruvian ceviche is a vibrant celebration of fresh coastal flavours, combining firm white fish with a zesty citrus marinade known as leche de tigre. The traditional addition of steamed sweet potato and corn provides a wonderful contrast to the sharp lime juice and the gentle heat of the ají limo chillies. It is a sophisticated yet simple dish that relies on the quality of its fresh ingredients to deliver a clean, zingy finish.
As a diabetes-friendly option, this recipe is naturally low in fat and packed with lean protein.

Serve it chilled immediately after marinating to ensure the fish maintains its delicate, buttery texture and bright, refreshing taste.

How to make Peruvian Ceviche
Set a fine-mesh sieve over a small bowl. Purée first 4 ingredients and 4 large ice cubes in a blender until smooth. Add onion; pulse 3-4 times. Strain liquid into a medium bowl. Stir in clam juice, if desired; season with salt. Cover and chill.
Pour water into a large pot fitted with a steamer basket to a depth of 1"; bring to a boil. Add sweet potato, cover, and cook until just fork-tender, about 30 minutes. Transfer to a plate; let cool.
Meanwhile, add more water to same pot, if needed, to measure 1"; bring to a boil. Add ear of corn to pot and steam until crisp-tender, 2-3 minutes. Transfer to a plate; let cool completely.
Halve potato lengthwise. Using a small melon baller, scoop out potato balls and place them in a small bowl; set aside. Cut kernels from cob. Reserve 80ml kernels (save extra kernels for another use).
Rub a large bowl with cut sides of chilli; discard. Place fluke, 2/3 of onion, leche de tigre, and 4 large ice cubes in bowl; stir well. Let marinate for 2 minutes; remove ice. Fold in potato and corn; season with salt.
Using a slotted spoon, divide ceviche into small bowls or onto plates. Drizzle ceviche with leche de tigre from bowl; garnish with remaining onion and coriander.
