There can only be one most expensive sandwich in the world, and that title belongs to what is also one of the most humble sandwiches out there: the grilled cheese. The New York-based restaurant Serendipity 3 holds the Guinness World Records title of the most expensive sandwich ever. It’s called the Quintessential Grilled Cheese, and it sold for $214.
The price lied in the ingredients. To start with, the bread was Champagne bread made with Dom Perignon and 24 karat gold flakes. White truffle butter was spread on the bread, and then filled with Caciocavallo Podolico cheese — a cheese made from the Italian Podolica cow, of which there are only 25,000 in the world. Another thing adding to the rarity of the cheese: The cows only lactate from May to June.
Hungry customers needed to order 48 hours in advance so the ingredients could be flown in. Today, however, the Quintessential Grilled Cheese is no longer on the menu. If you feel like spending a ridiculous amount of money, though, the restaurant still offers the Golden Opulence Sunday for $1,000.
