INGREDIENTS
- 1 pound sashimi-quality skinless meaty ocean fish filet (many fish work well here, but halibut or bass are always reliable)
- 1/3-1/2 cup fresh lime juice
- 1 medium-large red-ripe tomato seeded and finely chopped
- 1 small carrot, peeled and shredded
- Fresh hot green chiles to taste (usually 1 to 2 serrano or 1 jalapeno chiles), stemmed, seeded and finely chopped
- 1/4 cup (loosely packed) chopped fresh cilantro plus leaves for garnish if you wish
- Salt
- 10-12 5-inch tostadas
- 1 avocado for garnish (optional)
INSTRUCTIONS
Cut the fish into 1-inch cubes and place in the freezer on a parchment-lined baking sheet for a few minutes until firm but not hard. Grind through the coarse disc of a meat grinder. (Alternatively, you can hand-chop the fish, which will take focus and perseverance, or you can chop it in small batches in a food processor, which will result in a slightly less-uniform grind.)
In a medium bowl, combine the fish, 1/3 cup lime juice, tomato, carrot and green chile. Cover and refrigerate for a few minutes for the flavors to mingle.
Taste and season with salt (usually about 1 teaspoon). Stir in a little more lime if the mixture looks dry or could use additional spark. Pile a portion onto each tostada and garnish with cilantro and avocado if you wish.
