Ahi-Chile Tostadas

Ingredients

Tostadas

2 cups vegetable oil for frying4 (6-inch) corn tortillas ½ teaspoon kosher salt, divided

Ahi-Chile

1 pound trimmed sushi-grade ahi or bluefin tuna, cut into ¾-inch pieces¾ cup ½-inch fresh pineapple pieces3 ounces English cucumber, peeled, halved lengthwise, and sliced thin (½ cup)½ cup thinly sliced red onion ¼ cup extra-virgin olive oil ½–1 serrano chile, seeded, sliced into thin rounds1 tablespoon flake sea salt 1 teaspoon pepper ½ teaspoon Jugo Seasoning Sauce 3 tablespoons plus 2 teaspoons lime juice (2 limes)8 thin slices avocado

Before You Begin

You will need 1 full pound of trimmed tuna for this recipe. If the fish you're purchasing has any sinewy belly or bloodline attached, consider buying a little extra to account for trimming away and discarding those parts. The coarse flake sea salt in the ahi-chile is intended to add texture in addition to salinity. If substituting Diamond Crystal Kosher Salt, lower the amount to 2 teaspoons; if substituting Morton Kosher Salt, reduce the amount to 1½ teaspoons; if using table salt, reduce the amount to 1 teaspoon. If you like spice, don’t seed the serrano. Jugo Seasoning Sauce is a variety of Maggi seasoning that is darker and more concentrated than others. If you can’t find it, Maggi or Knorr brands of liquid seasoning can be substituted. Do not add the lime juice to the tuna until just before serving because it will immediately begin cooking the fish.

Instructions

    for the tostadas

  1. Line baking sheet with triple layer of paper towels. Heat oil in medium saucepan over medium-high heat to 350 degrees.
  2. Place 1 tortilla in hot oil and press flat with potato masher or tongs for 60 seconds. Flip tortilla and fry, without pressing, until stiff and very lightly browned, about 30 seconds. Transfer tostada to prepared sheet and sprinkle with ⅛ teaspoon kosher salt. Repeat with remaining tortillas and kosher salt. Let tostadas cool completely, about 10 minutes. (Tostadas can be stored in zipper-lock bag for up to 2 days.)
  3. for the ahi-chile

  4. Combine tuna, pineapple, cucumber, onion, oil, serrano, sea salt, pepper, and Jugo in medium bowl.
  5. To serve, place 1 tostada on each of 4 individual serving plates. Stir lime juice into tuna mixture until fully incorporated. Divide ahi-chile evenly among tostadas, then top each with 2 avocado slices. Serve immediately.

Why This Recipe Works

These playful tostadas are a favorite from the Mariscos German Beyer food truck in San Diego, whose owner Jorge Fuentes has been serving his creative takes on fish and shellfish since 2005. A fresh spin on aguachile (which means “chile water” in Spanish)—a preparation that originated in Sinaloa, Mexico, in which fish (often shrimp) is quickly marinated in a mixture of lime juice, chiles, and sometimes additional aromatics—these tostadas feature tender morsels of sashimi-grade tuna and sweet-tart pineapple. The fish and fruit are tossed in a punchy marinade and served over crispy toasted corn tortillas with cucumber, red onion, and avocado.
