Wash the cilantro, pat the fish dry, peel the garlic and ginger, and roughly chop the red onion and celery. Keep the fish and lime juice chilled in the refrigerator while you prepare the rest. Cold ingredients help keep the leche de tigre fresh and safe, especially if using it with raw fish.
6 oz very fresh white fish, 1 cup freshly squeezed lime juice, 1/4 small red onion, 1-2 cloves garlic, 1 piece fresh ginger, 1/4 cup fresh cilantro leaves and tender stems, 1-2 teaspoons finely chopped celery or celery chunk
Roll the limes on the counter with the heel of your hand to loosen the juice. Cut and squeeze them, avoiding too much pressure so you don’t extract bitter pith. Strain to remove seeds and measure about 1 cup of fresh lime juice.

In a high-speed or regular blender, combine the fish chunks, lime juice, cold fish stock or water, chopped red onion, garlic, ginger (if using), celery, cilantro, chili (start with half and add more later if needed), sea salt, black pepper, and ice cubes.

Blend on medium-high speed for about 20–30 seconds, just until the mixture looks smooth, creamy, and slightly foamy. Stop before the blender pitcher becomes warm; the leche de tigre should stay cold and pale, like a thin, milky sauce.
Taste and adjust: add more salt if needed; if the mixture is too sharp, blend in a splash of fish stock or 1–2 tablespoons of evaporated milk for a softer, creamier balance. If you want more heat, add additional chili and blend briefly.

For a very smooth, silky leche de tigre, pour the mixture through a fine-mesh sieve into a bowl or pitcher, pressing gently with a spoon. Skip this step if you prefer a rustic, slightly thicker texture.
Cover and refrigerate the leche de tigre for at least 30 minutes and up to 4 hours so the flavors can meld. Use as a ceviche marinade, a citrusy sauce for seafood, or serve very cold in small glasses as shots.
