Instructions

1. 1

   Whip the egg whites

   Using a stand mixer fitted with the paddle attachment, beat the egg whites at medium speed until stiff peaks form, stopping before they become dry. Take the bowl off the mixer.

2. 2

   Make the batter

   In a separate bowl, whisk together the flour, salt and cumin, then whisk in the Mexican beer. Fold this mixture into the egg whites in 4 additions, gently enough to keep them from deflating.

3. 3

   Heat the oil

   Add oil to a heavy, wide frying pan or casserole to a depth of 6 mm (¼ in), and heat over medium for at least 5 minutes. Test it with a wooden spoon or the tip of a piece of fish; bubbles should form around it. Put a cooling rack on a baking tray and cover it with kitchen paper, or line the tray with kitchen paper if you do not have a rack.

4. 4

   Season the fish

   While the oil heats, season the fish strips lightly with salt and pepper. Put flour on a plate, press each strip into it on both sides, shake off the excess and set the fish on the rack.

5. 5

   Fry until golden

   When the oil is hot, dip the floured fish strips into the batter one at a time and gently lower them into the oil. Fry in batches without crowding the pan for 2 to 3 minutes, until crisp and lightly golden, then turn and fry the other side for another 2 to 3 minutes.

6. 6

   Assemble the tacos

   Lift the fish out with tongs or a slotted spoon and place it on the paper-lined rack. Loosely cover with foil to keep warm. Serve in flour tortillas with Salsa Macha and Creamy Green Slaw, adding pickled onion if you like. For the optional garnish, marinate red onion and jalapeño in freshly squeezed lime juice and salt to taste.

What are Cali-Baja fish tacos?

Cali-Baja refers to the food traditions and flavours associated with California and Baja California. Fish tacos are closely linked with the coastal cooking of Baja, where fried or grilled fish is served in tortillas with fresh accompaniments.

This version uses a light beer batter folded with whipped egg whites for a delicate coating. Creamy slaw, punchy Salsa Macha and pickled onion bring coolness, heat and acidity to the crisp fish.

Nutrition and macros by portion

The nutrition label shows one serving as written: 490 calories, 27g protein, 48g carbs, 20g fat.

The fish and egg whites provide most of the protein, while the flour, beer and tortillas contribute carbohydrates. Frying oil and the batter account for much of the fat, with the toppings adding further variation depending on how much you use. Pair a taco portion with extra slaw or another vegetable side for a more balanced plate.

Why this batter works

Egg whites: Whipping them to stiff, not dry, peaks helps give the coating an airy texture. Fold the flour mixture in gradually and gently so the whites retain as much volume as possible.

Beer: A light Mexican beer keeps the batter fluid and adds flavour without making it overly heavy. Avoid a very dark, bitter beer, which can dominate the fish.

Choosing and preparing the fish

Firm white fish: Cod, haddock or halibut are good options because they can be cut into strips and handled during frying. Keep the pieces at roughly 2.5 × 10 cm so they cook in the stated time.

Dry coating: Season the strips lightly, then dust them in flour and tap off the excess. This gives the batter a surface to cling to.

Getting the oil ready

Depth: The recipe calls for 6 mm of oil in a wide, heavy pan. Let it heat over medium for at least 5 minutes, then check for lively bubbles around the wooden spoon or fish tip.

Batch size: Add only as many pieces as fit without crowding. Too much fish at once makes it harder to turn the strips and can slow the frying.

Crispness and doneness

Colour: Look for a crisp, lightly golden coating, usually after 2 to 3 minutes on each side. Use the appearance and timing together, since strip thickness and pan temperature can affect how quickly the fish cooks.

Handling: Lower each piece gently into the oil and turn it carefully with tongs or a slotted spoon. Tongs with heat-resistant coated ends can be gentler on the batter.

Toppings and serving

Contrast: Creamy Green Slaw offsets the hot, crunchy fish, while Salsa Macha adds a richer, spicy note. Pickled onion or the optional lime-marinated onion and jalapeño bring a bright, sharp finish.

Serve the fish in flour tortillas soon after frying, while the coating is still crisp. Keep the toppings ready before the last batch comes out of the pan.

Recipe notes & tips

• Cut the fish into similar-sized strips so the pieces cook at a similar pace.
• Have the batter, floured fish and draining rack ready before you start frying.
• Use a light beer rather than one with a strong bitter flavour.
• Fry in batches and give each strip space in the pan.
• Keep the fried fish loosely covered with foil while you finish the remaining batches.
• Set out the tortillas and toppings before frying the final batch.

Variations

• Change the fish: Use cod, haddock or halibut, keeping the strips a similar size.
• Use another oil: Choose safflower or rapeseed oil for frying, as listed in the recipe.
• Add lime-marinated garnish: Toss red onion and jalapeño with fresh lime juice and salt to taste.
• Adjust the heat: Serve more or less Salsa Macha according to your preference.
• Try a different tortilla: Use another flour tortilla size to suit how generously you want to fill each taco.

Common mistakes to avoid

• Deflating the egg whites: Fold in the flour mixture gently in 4 additions.
• Using dry peaks: Stop whipping when the whites are stiff but not dry.
• Skipping the oil test: Check for bubbles around a wooden spoon or fish tip before frying.
• Crowding the pan: Fry in batches so the strips have room to cook and turn.
• Leaving excess flour on the fish: Tap off the loose coating before dipping each strip in batter.
• Frying by time alone: Check for a crisp, lightly golden coating as well as the 2 to 3 minute timing per side.

How to store

Refrigerate leftover fish in a covered container for up to 2 days, separate from the tortillas and toppings. Reheat the fish in an oven or air fryer until hot to help the coating crisp again; avoid the microwave if you want to preserve its texture.
