A jam maker has marked its 125th anniversary by producing the world's most expensive marmalade.

F Duerr & Son's Fine Cut Seville Orange Marmalade with Whisky, Champagne and Gold costs £5,000 a jar.

That means it would cost an estimated £76 to spread on just one slice of toast, reports the Telegraph.

It contains finest Seville fruit with vintage Dalmore 62 whisky from Whyte & Mackay, valued at £32,000 per bottle, Pol Roger Cuvée Sir Winston Churchill 1996 vintage champagne and flakes of 24-carat gold leaf.

The Manchester-based firm's special marmalade is encased in a custom-made crystal jar valued at £1,100.

Managing director Mark Duerr said: "It's unbelievably good - we tasted it at a board meeting last week for the first time, and were amazed. The whisky comes through immediately. The champagne's more subtle."

The initial plan was to make the exclusive preserve a one-off production, with the one-kilo jar being auctioned on eBay to raise money for the Manchester Kids charity.

However, Duerr's has been so impressed by the taste that it is considering making a more affordable version as a normal product.
