Heat the deep fat fryer to 170c. 1 Sieve the flour and salt into a large bowl. Make a well in the centre to break the egg into. 2 Add half the beer and whisk to form a smooth batter. Gradually whisk in the remaining beer and soda water. Leave to rest. Heat 1" oil in a large saute pan. 3 For the Boxty: Grate the remaining potato and onion and squeeze in a clean tea-towel to remove excess moisture. Place in the bowl with the mashed potato. 4 Break the egg into a small dish, beat and add to the potato mixture. Add 2-3 tbsp flour, season and mix well. 5 Drop spoonfuls of the mixture into the saute pan and shallow fry for 3-4 minutes on each side, until golden brown and crispy. 6 For the Salad: Shred the lettuce and place in a bowl with the watercress. Deseed the pepper and slice lengthways. Add to the bowl of salad. 7 For the Prawns: Remove the head, shell and tail. Dip each prawn in the flour and batter, and deep fry for 3-4 minutes, turning once during cooking. Recipe by: Cant Cook Wont Cook
