Fish Aguachile with Creamy Avocado Sauce

Creamy Avocado Aguachile de Pescado

• ½ lb sushi-grade fish (yellowtail, kanpachi sea bass, halibut, or tuna), cut into small cubes
• ¼ cup ripe mashed avocado
• ½ cup fresh cilantro leaves and tender stems
• ½–1 serrano chile, stem removed (keep seeds for more heat)
• 2 tbsp chopped cucumber, peeled and seeded
• 1 small garlic clove
• ¼ cup fresh lime juice
• Zest of ½ lime
• ¼–½ cup cold water, plus more if needed
• Salt, to taste
• 2 tbsp finely minced red onion
• 2 tbsp finely minced cucumber
• Fresh cilantro leaves, for garnish
• Flaky sea salt, for finishing
• Tostadas or tortilla chips, for serving

1. Prepare the avocado aguachile base: In a blender combine the mashed avocado, cilantro (leaves and tender stems), serrano chile (start with half and add more if you want extra heat), garlic, fresh lime juice, lime zest, peeled and seeded cucumber, and a pinch of salt. Blend on high until completely smooth and silky.
2. Adjust texture and seasoning: Taste and adjust the salt and lime as needed. If the sauce is too thick to pour comfortably, add cold water a tablespoon at a time until it reaches a pourable but still creamy consistency. Chill the sauce in the refrigerator until very cold, at least 15 minutes.
3. Toss the fish: In a small mixing bowl combine the cubed sushi-grade fish with two pinches of flaky sea salt, the finely minced red onion, and the finely minced cucumber. Gently toss to combine so the onion and cucumber are evenly distributed without breaking up the fish.
4. Plate the fish tower: Place a round cookie cutter or ring mold in the center of a wide, shallow plate or bowl. Spoon the cubed fish mixture into the mold, pressing gently to compact into a short, even tower. Use a spoon to level the top, then carefully lift the mold straight up to reveal the neat tower in the center of the plate.
5. Pour the avocado base: Slowly pour the chilled avocado aguachile around the base of the fish tower, letting it pool and spread evenly. The sauce should surround but not overwhelm the fish tower.
6. Garnish and serve: Finish with a few fresh cilantro leaves and a light sprinkle of flaky sea salt over the fish. Serve immediately with tostadas or tortilla chips on the side for scooping.

• Use truly sushi-grade fish since this dish is served raw. Ask your fishmonger for sashimi-quality pieces and plan to use the fish the same day you buy it for the best texture and safety.
• Chill the avocado base well before plating. A very cold sauce against the room-temperature fish provides the refreshing contrast that defines aguachile.
• If you don’t have a ring mold, a clean, empty can with both ends removed works as a makeshift mold for pressing the fish into a tower.
• Minced red onion and cucumber should be very fine—large pieces will disrupt the delicate texture and every bite. Finely mince for the best mouthfeel.
• Adjust heat to taste by varying the amount of serrano or by removing the seeds for a milder result. Always add the chile gradually and taste before serving.
• To keep any leftover avocado base, store it tightly covered in the refrigerator and use within 24 hours. Do not store the raw fish; it is best consumed immediately.
• Variation ideas: add thin slices of radish for crunch, or a few drops of good olive oil over the fish for richness. Garnish with microgreens or sliced jalapeño for extra visual appeal.

Present this dish as an elegant starter or light main. The tower format creates a restaurant-style plate: center the fish, surround it with the smooth avocado-lime sauce, and finish with bright cilantro and flaky salt. Serve with warm tostadas or crisp tortilla chips so guests can scoop and savor each bite. Pair with a crisp white wine, cold beer, or a citrus-forward cocktail for a refreshing accompaniment.
