For a classic recipe that started life as just a handful of key ingredients, the humble hamburger has certainly come a long way from its fast food origins.

The basic patty of ground meat sandwiched between a sliced bread roll has evolved into a full-on gourmet affair.

These are the 10 most expensive burgers in the world; culinary works of gastronomic excellence with an astronomical price tag to match.

First: Fleur de Lys in Mandalay Bay, Las Vegas, Nevada, is home to the $5,000 FleurBurger 5,000 - the most expensive burger in the world

Second: A $777 Kobe Beef and Maine Lobster Burger, consisting of Kobe Beef and fresh Maine Lobster, caramelised onions, imported brie cheese, prosciutto, 100-year aged balsamic vinegar

Third: The $666 '666 Burger' from New York City, is foie gras-stuffed Kobe patty topped with gruyere cheese melted with champagne steam, lobster, truffles, caviar, and a BBQ sauce made with Kopi Luwak coffee beans

Eight of the patties can be found in upmarket restaurants in the U.S., while a ninth is on offer in London and a tenth in Indonesia. One of them even comes with a diamond-encrusted solid gold toothpick.

However - with the cheapest on sale for £100 and the most expensive being offered for $5,000 - it's debatable whether your average burger-loving diner will ever be wealthy enough to sample the delights of these dishes.

The most expensive on the list is the FleurBurger 5000, at Fleur de Lys in Mandalay Bay in Las Vegas, Nevada, which costs a whopping $5,000.

Containing foie gras and a special truffle sauce, it is served on a brioche truffle bun with black truffles on the side and comes with a bottle of Chateau Petrus 1990, poured in Ichendorf Brunello stemware.

And the $777 Kobe Beef and Maine Lobster Burger from Le Burger Brasserie in Paris Las Vegas, Nevada, consists of Kobe beef and fresh Maine lobster, caramelised onions, imported brie cheese, prosciutto, 100-year aged balsamic vinegar. It is served with a bottle of Rose Dom Perignon champagne.

It's class all the way for the '666' burger in New York. With a price tag of $666, the foie gras-stuffed Kobe patty is topped with gruyere cheese that has been melted with champagne steam, lobster, truffles, caviar, and a BBQ sauce made with Kopi Luwak coffee beans.

Fourth: At $499, the Absolutely Ridiculous Burger served up at Mallie's Sports Bar and Grill in Southgate, Michigan, is not only one of the world's most expensive - it's also the largest at 185.6lbs

Fifth: There's a baffling array of ingredients in the $295 Serendipity Burger from Serendipity 3 in New York City. But don't fret - a diamond-encrusted solid gold toothpick is included in the meal price

Some might say the $499 Absolutely Ridiculous Burger, from Mallie's Sports Bar & Grill in Southgate, Michigan, is precisely that.

Not only is it one of the most expensive, the 185.6lb burger also holds the Guinness World Record holder for being the world's largest.

If you're wary of parting with $295 for the Serendipity Burger from New York's Serendipity 3 restaurant, fret not - the meal even comes with its very own diamond-encrusted solid gold toothpick.

The patty of Japanese Waygu beef is infused with ten herb white truffle butter, seasoned with Salish Alderwood smoked Pacific sea salt, topped with cheddar cheese hand-formed by James Montgomery in Somerset, England, and 18-month 'cave-aged' shaved black truffles.

A fried quail egg, a white truffle-buttered Campagna Roll - itself, topped with a blini, creme fraiche, and Paramout Caviar's exclusive Kaluga caviar - finishes the dish.
