How to Make It
In a blender, combine the lime juice, clam juice and garlic with half each of the habanero and onion and 1 tablespoon of the cilantro. Blend until smooth. Strain the marinade through a fine strainer; season with salt.
Spread the fluke in a single layer in a shallow glass or ceramic dish. Pour the marinade over the fluke. Cover and refrigerate until the fluke starts to turn white, at least 1 hour and up to 4 hours.
Stir the remaining habanero, onion and cilantro into the fluke and season with salt. Spoon the ceviche into Chinese soup spoons or small bowls and garnish with Peruvian corn kernels.
Peruvian corn is sold frozen on the cob at Latin markets and in the ethnic section of many supermarkets. Dried kernels are available at tienda.com.
