Instructions

1. 1

   Make the slaw

   Toss the green and red cabbage with the coriander, lime juice, vinegar and a pinch of salt. Mix thoroughly and leave it to rest while you prepare the other components.

2. 2

   Mix the sauce

   Stir together the soured cream, mayonnaise, lime juice, hot sauce and garlic powder. Taste and add salt if needed, then refrigerate until serving.

3. 3

   Cut the fish

   Pat the cod fillets completely dry with kitchen paper. Cut them into strips roughly 8 cm (3 inches) long and 2.5 cm (1 inch) wide.

4. 4

   Prepare the batter

   Whisk the flour, cornflour, garlic powder, smoked paprika, cumin, salt and pepper together. Gradually stir in the cold sparkling water or beer until the batter coats the back of a spoon; a few small lumps are fine, so avoid overmixing.

5. 5

   Heat the oil

   Pour vegetable oil into a heavy pan to a depth of about 1.3 cm (1/2 inch) and heat over medium-high heat. Drop in a little batter to check: it should sizzle straight away.

6. 6

   Fry the fish

   Dip each fish strip in the batter, let the excess drip off, then carefully place it in the hot oil. Fry in batches for about 2 to 3 minutes per side, until golden and crisp, and drain on a plate lined with kitchen paper.

7. 7

   Warm the tortillas

   Heat the tortillas in a dry pan over medium heat for 30 seconds on each side, or wrap them in a damp kitchen-paper towel and microwave for 45 seconds.

8. 8

   Assemble the tacos

   Divide the slaw, fried fish, creamy sauce and avocado slices among the tortillas. Finish with a squeeze of fresh lime and sliced jalapeño, if using, and serve straight away.

What are Baja fish tacos?

Baja-style fish tacos are associated with the Baja California peninsula in Mexico, where seafood is often served in tortillas with crisp vegetables and lively toppings. This version uses battered, fried fish for a crunchy centre, balanced by sharp cabbage slaw and a cool, creamy sauce.

The separate components make the tacos easy to customise at the table. A squeeze of lime brings the flavours together just before eating.

Nutrition and macros by portion

The nutrition label shows one serving as written: 680 calories, 40g protein, 62g carbs, 34g fat.

The fish supplies most of the protein, while the tortillas and flour-based coating contribute much of the carbohydrate. Frying oil, avocado, soured cream and mayonnaise provide much of the fat. Serve with extra vegetables or a green salad to add freshness alongside the tacos.

Why the batter works

Cornflour: Combined with plain flour, it helps make a light, crisp coating around the fish.

Cold liquid: Sparkling water or beer goes into the batter cold, and the recipe calls for only gentle mixing. A few lumps are fine; overworking can make the coating heavier.

Keep the fish dry

Dry fillets: Pat the cod thoroughly with kitchen paper before cutting it into strips. This helps the batter cling instead of sliding off a wet surface.

Even strips: Cutting the fish to roughly the same size helps the pieces cook at a similar rate. Tilapia can be used instead, as the recipe suggests.

Frying cues to watch

Ready oil: A small drop of batter should sizzle immediately when it hits the oil. If it does not, wait for the oil to heat before frying.

Golden coating: Cook the fish in batches for about 2 to 3 minutes per side, looking for a crisp, golden exterior. Drain the cooked pieces on kitchen paper.

Make the toppings ahead

Slaw: Toss the cabbage with the herbs, lime, vinegar and salt first, then leave it to rest while you prepare the rest. This gives the flavours time to mingle without adding extra steps at the end.

Sauce: Stir it together and keep it refrigerated until assembly. Warm the tortillas just before serving so they are pliable.

Build and serve

Layer slaw, hot fried fish, sauce and avocado on each tortilla, then finish with lime and optional jalapeño. Assemble just before eating so the fish stays crisp.

Serve with extra lime wedges and, if you like, a simple side of beans or a green salad. Keep the toppings separate if people want to build their own tacos.

Recipe notes & tips

• Set out the slaw, sauce, fish and tortillas separately so the tacos can be assembled just before eating.
• Keep the batter cold while you work and stir it only until the ingredients come together.
• Fry in batches rather than crowding the pan, so the fish has room to crisp.
• Use a thermometer if available, but still check for the immediate sizzle from a small drop of batter.
• Warm the tortillas shortly before serving so they stay soft and flexible.
• Offer jalapeño and lime at the table so everyone can adjust the heat and acidity.

Variations

• Use tilapia: Swap it for the cod as suggested, cutting it into similar-sized strips.
• Choose beer: Use cold beer in place of sparkling water for the batter.
• Turn up the heat: Add more sliced jalapeño at serving.
• Add extra crunch: Increase the shredded cabbage in the slaw.
• Make it mild: Leave out the jalapeño and use less hot sauce in the dressing.

Common mistakes to avoid

• Wet fish: The batter may slide off; pat the fillets completely dry before cutting.
• Overmixed batter: It can become heavy; stop stirring once the liquid is incorporated, even if a few lumps remain.
• Oil not hot enough: The coating may not crisp properly; wait until a small drop of batter sizzles immediately.
• Crowded pan: Too many pieces at once can interfere with crisp frying; cook the fish in batches.
• Assembling too early: The coating can soften against the slaw and sauce; fill the tortillas just before serving.

How to store

Refrigerate leftover fish, slaw and sauce in separate airtight containers and use within 2 days. Reheat the fish in an oven or air fryer until hot and crisp; warm tortillas separately and assemble just before eating. The fish coating will soften if reheated in a microwave.
