The delicacy was created by celebrity chef Martin Blunos, who hand-crafted the luxury snack using cheddar blended with expensive white truffles.

It is dressed with 100-year-old balsamic vinegar and the sourdough bread - which costs £5 alone - is sprinkled with powdered E175. That's gold dust to you and me.

The gourmet dish is the main attraction at the Frome Cheese Show in Somerset where the Food Poker star is judging a sandwich-making competition.

Blunos worked with expert cheese-makers at local west country producer Pilgrim's Choice to create the special white truffle blend, which gives the sandwich its hefty price tag. 

He said: "We Brits are known to love our cheese sandwiches, and here's one that not only comes with a royal price tag but is fit for the banqueting table.

'The white truffle fuses beautifully with the West Country Farmhouse Cheddar and the edible gold leaf gives it a really special look.'

'In fact, washed down with a bottle of Krug, what more could you want?' 

Blunos selected the highest quality ingredients to create the double-layered dish.

He worked with experienced cheddar producers at Pilgrim's Choice to create the bespoke white truffle cheese, which itself costs £92.

The chef used a £5 loaf of sourdough dressed with extra virgin olive oil and then layered cheese, slices of quail's egg, heirloom black tomato, epicure apple, and fresh figs.

He added dainty mustard red frills, pea shoots and red amaranth for a salad layer and topped the whole masterpiece with edible gold dust.

The cost of the entire sandwich put together runs to £111.95.

There is no current official world record for the most expensive cheese sandwich but Blunos and Pilgrim's have applied to the Guinness book to have their sandwich recognised.

The standing record for the most expensive commercially available sandwich is the von Essen Platinum Club Sandwich, which was made at the Cliveden House hotel in Taplow, Berkshire.

It featured Iberico ham, poulet de Bresse, white truffles, quail eggs, semi-dried tomatoes and fermented sour dough bread, weighed half a kilogram, and cost £100.

It's probably a little extra if you want it toasted.
