I've seen guesstimates online for anything up to 1400 for a large battered cod and chips. if it's a regular portion and not a minifish special then I think your looking at closer to 1100 than 700 I'm afraid the batter just holds so much of the frying oil!!
Fish & chips Portions are often huge and nearly everything is deep fried. Batter adds more calories to fish, chicken and sausages so ditch some of it or opt for healthier, unbattered alternatives such as grilled fish or roast chicken. Easy ways to slash the baddies Halve your portions - a large portion of battered cod and chips contains a massive 1,385 calories and 77g of fat, whereas a small portion contains 685 calories and 38g of fat. Choose cod or haddock rather than plaice or rock as they're lower in calories and fat - a small battered haddock is 280 calories; cod, 295 calories; plaice, 385 calories; and rock, 445. Before eating, empty your fish and chips on to kitchen paper and dab to remove excess grease. Serve your fish and chips with mushy peas or baked beans - they're low in fat and packed with fibre to help fill you up. Skip extras like curry sauce, gravy and white bread and butter. They just add extra calories to a meal that's already loaded with them. Instead of... Large battered rock with large chips, gravy and 2 slices of bread and butter: 1,920 calories, 115g fat Order... Small battered haddock with small chips and mushy peas: 770 calories, 39g fat Save: 1,150 calories, 76g fat
