Leche de tigre, literally “tiger’s milk,” is the citrus-based, spicy marinade used to cure the fish in classic Peruvian ceviche. This makes a sizable batch; extra can be frozen for up to a month or repurposed, like in our Hair of the Tiger Cocktail.

What You Will Need
- 2 cups fresh lime juice
- 5 oz. firm white fish such as fluke, seabass, flounder, or sole
- 1 cup fish stock
- 1⁄2 large yellow onion, sliced (1 cup)
- 3 large garlic cloves, thinly sliced
- 2 celery ribs, coarsely chopped
- 2 tbsp. finely grated fresh peeled ginger
- 2 tsp. finely chopped cilantro stems
- 1 tsp. ají limo paste
- 2 1⁄2 tsp. kosher salt
Set a fine mesh strainer over a large bowl or measuring cup. Set aside.
In a high-powered blender, combine the lime juice, fish, fish stock, onion, garlic, celery, ginger, cilantro stems, ají limo paste, and ⅔ cup cold water. Blend until the mixture is completely liquefied, about 5 minutes. Add the salt and ⅓ cup ice cubes; blend till well combined, 30–60 seconds more.
Strain through the prepared sieve, reserving the liquid and discarding any solids. Cover and refrigerate the liquids until ready to use, up to 1 day, or freeze for up to one month. Thaw completely and chill before using.
