* This batter crisps brilliantly and can be used with white-fleshed or oily fish fillets, prawns, cuttlefish or squid. Flat or just-opened beer can be used for the batter. To prevent chips becoming soggy, cover the oven tray with absorbent paper (paper towels).
Whisk the flour, egg and beer together in a medium bowl until smooth; cover and refrigerate batter for one hour.
Cut the potatoes into 1cm-wide slices, cut slices into 1cm-wide strips and dry well. Heat the oil in a large pan and deep-fry the chips in batches until browned and cooked. Place them on absorbent paper on a large oven tray and keep them hot in a moderate oven.
Reheat the oil. Dip the fish in batter and deep-fry in hot oil until browned and crisp. Serve fish and chips with tartare sauce.
Tartare sauce: Combine all the ingredients in a medium bowl and mix well.
Tip: The best potatoes to use for deep-fried chips are Atlantic, Russet Burbank, Patrone, Bintje, Nicola, Spunta and Toolangi Delight.
