A family of Norfolk butchers are celebrating the Canaries' sizzling promotion season by producing a range of green and yellow sausages.

The 'On the Ball Bangers', named after the Carrow Road anthem, are on sale at M & M Rutland's shop on Briston Road in Melton Constable.

Each coloured sausage is made from free-range pork and natural ingredients – peas, pesto and mint for the green version, while the yellow comes from a tangy blend of Norfolk mustard and honey, with a pinch of turmeric.

Mike and Marion Rutland run the shop alongside their son James, his sisters Tracy Sturman, Kit Mavilio and Carol Newman, and butcher Gary Howes.

And, as they are all Norwich City fans, they hope the commemorative sausage will find its way on to grills and frying pans as Canaries fans spend the barbecue season looking forward to Premier League football.

James Rutland, who came up with idea, said: 'I knew we had to do something to mark Norwich City's promotion – it is such a brilliant, brilliant event for Norfolk. It had to be green and yellow, so I got my thinking cap on as to what would be tasty and still look effective, without using anything artificial.

'Each sausage has a distinct flavour, but they complement each other really well. The honey and mustard is initially sweet, with a kick of mustard at the end. The pea and pesto is a lovely, delicate, fresh spring flavour.'

Fifty pence from every pound of sausages sold will be donated to the East Anglian Children's Hospices charity.

The Rutlands are cooking up something of a reputation for making novelty bangers. A Norfolk Hero sausage released on Trafalgar Day in honour of Lord Nelson raised �450 for Help for Heroes, and the Royal Wedding was celebrated with a tongue-in-cheek Bloody Mary variety flavoured with vodka, Tabasco sauce and tomatoes.

'I spend far too much time thinking about sausages,' said James. 'I have a notebook next to my bed in case an idea comes to me in a dream. I need to get out more, really.'

Another – albeit unintended – family link to the football club is that James' sister Carol is regarded as a dead-ringer for City supremo and culinary icon Delia Smith. Carol, 51, said she had been mistaken for her illustrious lookalike on several occasions, including once in the chef's Yellows restaurant at Carrow Road.

'It is a compliment when people say I look like Delia,' she said. 'I am very flattered and I wish I could cook as well as she can. Perhaps it will help us sell some of these sausages – you never know.'
