Step 1

Combine flour and salt in a bowl. Make a well in the centre. Gradually add soda water or beer, using a whisk to stir until well combined.

Step 2

Add oil to large saucepan or wok. Heat over medium heat to 190C (when oil is ready, a cube of bread turns golden brown in 10 seconds).

Step 3

Dip 4 pieces of fish, one at a time, into batter to evenly coat and deep-fry for 3-4 minutes or until crisp and golden. Transfer to a plate lined with paper towel. Repeat with remaining fish pieces, reheating the oil between batches.
