  • 1 tablespoon lime juice

  • 1 heaped teaspoon sea salt

  • 120ml mayonnaise

  • 120ml soured cream

  • 2 teaspoons lime juice, plus extra to taste

  • 1 teaspoon finely grated lime zest

  • Pinch of sea salt

  • 2 tablespoons mayonnaise

  • 3/4 teaspoons lime juice

  • 2 drops jalapeño Tabasco sauce

  • 1/2 small head green cabbage, thinly sliced

  • Sea salt and ground black pepper

  • 60ml olive oil

  • 1/2 teaspoons chilli powder, or to taste

  • 1 1/2 teaspoons dried oregano

  • 1/2 teaspoons ground cumin

  • 1/4 cup coriander leaves, chopped

  • 1 green jalapeño, chopped

  • 450g flaky white fish filets

  • Sea salt and ground black pepper

  • Corn tortillas, for serving

To make the pickled red onion, place the onion and jalapeño in a heatproof medium bowl. In a small saucepan, combine the vinegar, lime juice and salt. Bring to the boil over high heat, stirring until the salt dissolves, then pour over the onion and jalapeño. Allow to stand at room temperature for at least 1 hour before using. (Leftovers will keep up to 1 week in the fridge.)

To make the Baja cream, whisk the mayonnaise, soured cream, lime juice, lime zest and salt in a small bowl, then taste for seasoning and lime juice.

To make the cabbage slaw, mix together the mayonnaise, lime juice and Tabasco in a bowl. Toss the cabbage with the mayonnaise mixture, season to taste and refrigerate.

To marinate the fish, mix the olive oil, chilli powder, oregano, cumin, coriander and jalapeño in a non-reactive dish. Add the fish and marinate for 20 minutes.

When ready to cook the fish, heat a non-stick frying pan over medium–high heat. Remove the fish from the marinade, place in the hot pan and season with salt.

Cook the fish for 4 minutes, then turn over, season again with salt and cook for another 2 minutes or until just cooked through, depending on the thickness.

Remove the pan from the heat and flake the fish with a fork, scraping up and mixing in any marinade that has stuck to the bottom.

Heat the tortillas according to the directions on the packet. To assemble the tacos, place a heaped spoon of the fish onto the centre of a warm tortilla. Top with the pickled onion and jalapeño, Baja cream, Baja cabbage slaw and tomato salsa.
