Fish Tacos: Mexican Battered Fish with Lime Crema
These authentic fish tacos rely on a light, sparkling water batter to ensure the tilapia remains tender inside a golden crust. You must keep the oil at 180°C (356°F) to prevent the coating from absorbing excess fat. Set the batter aside to rest for no longer than 10 minutes so it does not oxidise. This process maintains the lightness of the fish, which balances the richness of the creamy lime crema and the crunch of the cabbage.

Instructions
-
Mix the batter
Whisk the flour, baking powder and salt in a large bowl. Pour in the sparkling water and whisk until the mixture is smooth and lump-free. Let it rest for 10 minutes so the gluten relaxes for a lighter coating.
-
Prepare the fish
Pat the tilapia strips dry with paper towels to ensure the batter sticks. Season with black pepper and toss in 1 tbsp of olive oil. This prevents the fish from sticking to the bowl.
-
Fry the fish
Heat vegetable oil to 180°C (356°F). Dip fish strips into the batter and fry for 2-3 minutes per side. Remove them when the coating is golden brown and the fish flakes easily.
-
Whisk the crema
Combine mayonnaise, sour cream, lime juice, zest, garlic and sriracha in a small bowl. Stir until smooth. Keep it chilled to maintain a thick, creamy consistency.
-
Toast the tortillas
Heat a dry skillet over medium heat. Brush each tortilla with olive oil and toast for 15 seconds per side. This makes them pliable and prevents them from cracking.
-
Assemble the tacos
Place fish strips on the warm tortillas. Top with cabbage, onion, cilantro and cotija cheese. Finish with a drizzle of lime crema and a squeeze of fresh lime for acidity.
Ensure your oil stays at 180°C (356°F) using a thermometer. If the oil is too cold, the batter absorbs grease and becomes soggy. Avoid letting the batter sit for too long, as it can oxidise and lose the lightness required for a crisp finish.
Getting the texture right
Keep the oil at 180°C (356°F) to ensure the batter crisps immediately. Use a thermometer to monitor the heat. Do not let the batter rest for more than 10 minutes. If it stands too long, it oxidises and loses the lightness required for a crisp coating.
What to serve with it
Pair these tacos with a mango-avocado salsa for tropical sweetness. A bright black-bean and corn salad dressed in lime and olive oil also works well. For extra richness, drizzle a simple avocado crema made by blending ripe avocado with sour cream and lime juice over the fish.
Storing and reheating
Keep assembled tacos at room temperature for no longer than 2 hours. Store fried fish and tortillas separately in the freezer for up to 3 days. Reheat the fish by frying in a little oil or using a microwave to regain the texture.
Choosing the cut
Cut tilapia fillets into 4-cm strips to ensure they cook evenly. Pat the fish dry with paper towels before seasoning. This removes surface moisture, which allows the batter to adhere properly and prevents the coating from sliding off during the frying process.

What is the sauce they use on fish tacos?
A lime crema is used, made from mayonnaise, sour cream, lime juice, zest, and garlic. This provides a tangy, creamy contrast to the savoury fish and crisp cabbage slaw.
