Ingredients

For the batter -

75g/2½oz cornflour

75g/2½oz plain flour

1 free-range egg, lightly beaten

188ml/6½fl oz beer

For the prawn tempura -

vegetable oil, for deep-frying

50g/2oz plain flour

1.5kg/3lb 5oz uncooked king prawns, shells and central veins removed

Soy sauce, to serve

Directions

For the batter, sift the cornflour and flour together into a medium bowl.

Make a well in the centre and add the egg and beer and whisk from the centre outwards, until just combined (it is okay if the batter is a little lumpy). Allow the batter to stand for a few minutes in a cool place.

Heat the oil in a deep heavy-bottomed pan until a breadcrumb sizzles and turns brown when dropped into it. (CAUTION: hot oil can be dangerous. Do not leave unattended.)

Place the flour onto a plate and dredge the prawns into it to cover well. Dip the prawns into the batter and carefully add to the hot oil to deep-fry in batches for 2-3 minutes, or until crisp and golden.

Carefully remove with a slotted spoon and drain on kitchen paper.

Serve in bowls with a bowl of soy sauce for dipping.
