Pollock tacos with avocado salsa

Put the avocado, onion and coriander in a bowl. Squeeze over the juice of 1⁄2 lime, season and toss together; set aside. In a separate bowl, mix the soured cream, cumin, the remaining lime juice and 1 tsp water; season and set aside.

Heat the oil in a large, heavy-based sauté or frying pan over a medium-high heat. In a large bowl, combine the flour, paprika, bicarbonate of soda and salt, then whisk in the soda water. Put the fish in the batter. Lift half the fish out of the batter and carefully lay it in the pan. Fry for about 2-3 minutes on each side, then lift out and drain on kitchen paper. Repeat until all the fish is cooked.

Heat the tacos according to pack instructions. Top with the avocado salsa and fish, then drizzle with the cumin soured cream. Scatter over the red chilli and extra coriander leaves, then serve with slices of lime on the side.
