Ingredients

  • 1 lb Cod, Mahi Mahi, or Halibut cut into 3 inch strips
  • 1 cup all-purpose flour
  • 2 tbsp cornstarch (optional)
  • 4 tbsp San Diego Sauce
  • 1 cup Cold Mexican Lager (Beunaveza, Pacifico, Modelo, Corona)
  • 1/4 cup mayo
  • 1/4 cup crema (sour cream can be used as substitute)
  • 3 cup shredded cabbage or coleslaw mix
  • 12 ct corn tortillas
  • 2 cup neutral oil vegetable, corn, canola, avocado

Instructions

  • Make the San Diego Sauce Crema & Slaw:
  • In a medium bowl, whisk mayonnaise, Mexican crema, and 2 tbsp San Diego Sauce. Toss half with the shredded cabbage to make the slaw; set the other half aside for drizzling.
  • Prepare the Batter:
  • In a large bowl, whisk 1 cup flour and optional cornstarch. Add 2 tbsp San Diego Sauce, then slowly whisk in the cold beer until it reaches the consistency of heavy cream. Do not over-mix.
  • Fry the Fish:
  • Heat 2 inches of oil to 375°F. Pat fish dry, dredge lightly in flour, dip into batter, and fry for 2–3 minutes per side until golden. Drain on a wire rack.
  • Assemble:
  • Warm tortillas over a flame. Layer with the dressed cabbage, the fried fish, a drizzle of the remaining crema, and a squeeze of lime.

Notes

Chef’s Notes & Tips

  • The "Shatter" Crunch: For the crispiest results, use Mexican Lager (like Pacifico). The specific carbonation level and light malt profile react with the cornstarch to create an airy, "shatter-like" texture. Keep the beer ice-cold until the very last second!
  • Don't Over-mix: Small lumps in the batter are okay. Over-whisking develops gluten, which makes the coating "bready" or chewy instead of crisp.
  • Temperature Control: If you don't have a thermometer, test the oil by dropping a bit of batter in; it should sizzle and float immediately. If it sinks, the oil is too cold; if it browns in under 30 seconds, it's too hot.
  • The San Diego Foundation: In San Diego, the cabbage goes under the fish. This prevents the hot fish from steaming the tortilla, keeping the base sturdy and the fish crisp.
  • Fish Selection: While Cod is the standard, Mahi Mahi or Halibut offer a firmer "steak-like" bite that holds up better to the heavy San Diego Sauce-infused batter.

Make-Ahead & Storage

  • Pro Tip: You can make the Chipotle Crema and Slaw up to 24 hours in advance. The flavors actually improve as the San Diego Sauce melds with the crema.
  • Leftovers: Fried fish is best fresh, but if you have leftovers, reheat them in an Air Fryer at $375^{circ}text{F}$ for 3–5 minutes to restore the crunch. Avoid the microwave, as it will make the batter soggy.

Substitution Idea

  • Alcohol-Free: If you prefer not to use beer, substitute with an equal amount of unflavored sparkling mineral water (like Topo Chico). In this recipe, I used Modelo's salt and lime NA can. You’ll lose the malty flavor, but keep the essential "lift" from the bubbles.
