100 Italian chefs gathered in Chelsea and created the world's largest tiramisu, measuring 440.6 meters, using 3,000 eggs, 400 kilograms of sugar, and 50,000 ladyfingers, surpassing the previous record of 273.5 meters and putting chef Mirko Ricci back at the top of Guinness with a giant-scale dessert.

World’s largest tiramisù, 440.6 meters long, made in London by 100 Italian chefs, broke Guinness record.

On April 26, 2026, a gastronomic event of unusual scale placed London at the center of a world record. More than 100 Italian chefs gathered at Chelsea Town Hall in the British capital to produce the largest tiramisù ever recorded. The result was a dessert an impressive 440.6 meters long, officially recognized by Guinness World Records as the largest in the world.

The mark easily surpassed the previous record of 273.5 meters, set in 2019 by an Italian team in Milan. The difference of more than 160 meters not only breaks the record but redefines the standard for this type of gastronomic challenge.

Project led by Mirko Ricci, who reclaims the world record

The initiative was led by Italian chef Mirko Ricci, who had previously won the title in 2017.

Giant dessert required complex logistics and large-scale production

To meet the standard required by Guinness, the tiramisù had to be assembled entirely on-site and follow strict rules of uniformity, height, and width.

The scale of the operation is impressive:

approximately 50,000 savoiardi biscuits
more than 3,000 eggs used
continuous assembly over hundreds of meters

Each section of the dessert needed to maintain consistency, with a minimum height and uniform standard throughout its entire length. It wasn’t just about making a giant dessert, but about maintaining quality and standardization on an extreme scale.

Event held live for Guinness World Records validation

One of Guinness’s requirements is that the record be built and verified in real-time, under official supervision. The entire assembly process was monitored by judges, who verified:

exact dimensions
ingredient quality
structural continuity

The tiramisù couldn’t just be big — it needed to be technically valid as a dessert throughout its entire length.

Tiramisù’s dimension approaches iconic urban landmarks

At 440.6 meters long, the tiramisù enters a scale difficult to visualize in everyday life. For comparison, this size:

approaches the height of iconic skyscrapers
exceeds the length of well-known urban structures
requires assembly in large continuous spaces

The dessert ceases to be just a dish and begins to occupy a scale comparable to that of major urban works.

Traditional Italian recipe maintained even on a giant scale

Despite its size, the tiramisù followed the classic composition of the Italian dessert:

layers of coffee-soaked biscuits
mascarpone cream
cocoa powder

Maintaining the traditional recipe was one of the criteria for validating the record. Even on an extreme scale, the dessert had to respect its original identity.

Event also had symbolic and cultural character

Beyond the record, the project had a symbolic component. According to the organizers, choosing London as the event’s stage was a way to celebrate cultural and gastronomic relations, as well as highlight the importance of Italian cuisine in the world.

The giant tiramisu was even decorated with symbolic elements, including a crown, in homage to the United Kingdom. The event combined gastronomy, spectacle, and cultural representation in a single initiative.

Gastronomic records become increasingly complex and technical

Challenges of this type show how culinary records have evolved over the years. Today, they require:

detailed logistical planning
rigorous quality control
coordination of large teams
international technical validation

What was once just a gastronomic curiosity has transformed into highly structured operations.

Given this record, how far can the scale of modern gastronomy go?

With a dessert over 440 meters long, produced by hundreds of hands and validated as the largest in the world, Chelsea’s tiramisu enters history not just as a record, but as an example of how far gastronomy can go in scale and organization.

The feat shows that cuisine, traditionally associated with craftsmanship, can also operate on industrial and symbolic dimensions simultaneously.

The inevitable question remains: what will be the next limit to be overcome when gastronomy decides to compete on a global scale?

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.
