Ingredients
- 450g (1 lb) firm white fish fillets (such as cod, tilapia, or pollock), patted dry
- 125g (1 cup) all-purpose flour, plus extra for dusting
- 5g (1 teaspoon) fine sea salt, plus more to taste
- 5g (1 teaspoon) smoked paprika
- 240ml (1 cup) ice-cold water
- 1 large egg
- 8 small corn tortillas
- 200g (2 cups) finely shredded green cabbage
- 1 large ripe tomato, finely diced
- 1 ripe avocado, diced
- 120ml (1/2 cup) sour cream or Mexican crema
- 15ml (1 tablespoon) fresh lime juice, plus extra wedges for serving
- Vegetable oil, for frying
Instructions
- Prepare the fish by patting the fillets thoroughly dry with paper towels. This crucial step ensures the batter adheres perfectly. Cut the fish into uniform strips, approximately 2-3 cm (1 inch) wide and 8-10 cm (3-4 inches) long, aiming for pieces that will fit neatly into a tortilla.
- In a medium mixing bowl, combine the 125g (1 cup) all-purpose flour, 5g (1 teaspoon) fine sea salt, and 5g (1 teaspoon) smoked paprika. Whisk them together thoroughly to ensure all the spices are evenly distributed throughout the dry mixture.
- Create a shallow well in the center of your dry ingredients. Crack the large egg into this well and pour in the 240ml (1 cup) of ice-cold water. Gradually whisk the wet ingredients into the dry, starting from the center and working your way outwards, until a smooth, thin batter forms. A few small lumps are acceptable; avoid overmixing, as this can develop gluten and lead to a tougher batter. The ice-cold water is key for a truly crispy crust.
- Heat a heavy-bottomed pan, cast-iron skillet, or deep frying pan over medium-high heat. Add enough vegetable oil to reach a depth of about 2-3 cm (1 inch). Heat the oil to an optimal frying temperature of 175-180°C (350-360°F). If you do not have a thermometer, test the oil by dropping a tiny amount of batter; it should sizzle vigorously and float to the surface within a few seconds.
- While the oil heats, lightly dust each fish strip with a little extra dry flour. This initial dusting creates a dry surface that helps the wet batter stick better. Then, carefully dip each floured fish strip into the prepared batter, ensuring it's evenly coated on all sides. Allow any excess batter to drip off back into the bowl.
- Gently place a few battered fish strips into the hot oil, being careful not to overcrowd the pan, which can lower the oil temperature and result in soggy fish. Fry for 2-3 minutes per side, or until the fish is beautifully golden brown and deeply crispy. The internal temperature of the fish should reach 63°C (145°F) and it should flake easily with a fork. Using a slotted spoon or tongs, carefully transfer the fried fish to a wire rack set over a paper towel-lined baking sheet to drain excess oil. Immediately season the hot fish lightly with a pinch of additional salt. Repeat this process with the remaining fish strips.
- While the fish fries, warm your corn tortillas. This can be done by heating them individually directly over a medium gas flame for 10-15 seconds per side until slightly charred and pliable, or wrap a stack of them in a damp paper towel and microwave for 30-45 seconds, or heat them in a dry skillet over medium heat for 20-30 seconds per side. Keep the warm tortillas wrapped in a clean kitchen towel to maintain their warmth and flexibility.
- In a small bowl, whisk together the 120ml (1/2 cup) sour cream (or Mexican crema) and 15ml (1 tablespoon) fresh lime juice until the mixture is smooth and well combined. This creates a simple yet tangy and refreshing crema that perfectly complements the rich fish.
- Assemble your tacos by taking a warm tortilla, adding a generous portion of the crispy fried fish, then topping it with a handful of finely shredded cabbage, a spoonful of diced tomato, and a few pieces of diced avocado.
- Drizzle each taco generously with the freshly prepared lime sour cream mixture. Serve the tacos immediately with extra lime wedges on the side, allowing everyone to add an additional burst of citrus freshness to their liking.

Tools You’ll Need
- Large mixing bowls
- Whisk
- Measuring cups and spoons
- Sharp knife and cutting board
- Heavy-bottomed pan or deep skillet
- Slotted spoon or tongs
- Wire rack
- Paper towels
- Kitchen thermometer (optional, but recommended for frying oil)
Essential Success Tips
- Always pat the fish extremely dry before dredging in flour and batter. Moisture is the enemy of crispiness!
- Use ice-cold water for the batter. The temperature difference between the cold batter and hot oil creates steam, resulting in a lighter, crispier coating.
- Do not overcrowd the frying pan. Fry in batches to maintain the oil's temperature, which is crucial for achieving that perfect crisp without making the fish greasy.
- Season the fish immediately after it comes out of the oil. The salt adheres best to hot, freshly fried surfaces.
- Warm your tortillas properly. Warm, pliable tortillas are essential for good tacos; cold ones will crack and break.
Professional Cooking Secrets
- For an even lighter, tempura-like batter, consider using half all-purpose flour and half cornstarch in your batter mixture. A splash of vodka in the batter can also inhibit gluten development and evaporate faster, leading to a crisper result.
- Enhance your crema: Add a pinch of garlic powder and a finely minced chipotle in adobo to your lime sour cream for a smoky, spicy kick that elevates the entire taco.
- Rest your fried fish briefly. While tempting to serve immediately, letting the fish rest for a minute on the wire rack allows any residual oil to drain off and the coating to firm up even further, ensuring maximum crispness.

Notes
- Storage: Leftover fried fish can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in an oven or air fryer for best crispness. Keep toppings separate.
- Variations: Experiment with different fish types like snapper or mahi-mahi. For a spicier kick, add a dash of cayenne pepper to the batter or a pinch of chili flakes to your crema. Try different slaw mixtures with red cabbage or a squeeze of orange juice.
- Gluten-Free Option: Use a good quality gluten-free all-purpose flour blend for the batter. Ensure your tortillas are certified gluten-free.
Frequently Asked Questions
What kind of fish is best for these tacos?
Firm white fish fillets like cod, tilapia, pollock, or even haddock work best. They hold their shape well during frying and have a mild flavor that complements the taco toppings.
Can I bake or air fry the fish instead of frying?
While frying yields the crispiest result, you can certainly bake or air fry for a healthier option. For baking, spray battered fish with oil and bake at 200°C (400°F) for 15-20 minutes, flipping halfway. For air frying, spray lightly and cook at 190°C (375°F) for 10-15 minutes, shaking the basket occasionally, until golden and cooked through.
How can I make the tacos spicier?
To add heat, you can incorporate a pinch of cayenne pepper into the fish batter. Alternatively, finely dice a jalapeño or serrano pepper and add it to your cabbage slaw, or mix some hot sauce or a dash of adobo sauce from canned chipotles into your lime sour cream.
