A two-day effort in London has produced a new world record for the longest tiramisu, with Italian chefs and volunteers assembling a dessert spanning more than 440 meters, according to organizers and Guinness officials.
The attempt took place at Chelsea Old Town Hall, where around 100 Italian chefs worked alongside volunteers to surpass the previous record of 273.5 meters set in Milan in 2019.
The final measurement reached 440.58 meters, securing a new title recognized by Guinness World Records.
The initiative was led by Italian entrepreneur Mirko Ricci, who had previously held the same record in 2017 before losing it to another Italian team two years later.
Speaking about the decision to stage the attempt in the U.K. rather than Italy, Ricci described it as a gesture of appreciation toward the country.
He called tiramisu “the most incredible dessert that Italy has exported,” adding that the record attempt was also dedicated to the British monarchy, with the final presentation featuring a decorative golden crown.
The event was supported by the London branch of the Federation of Italian Chefs, as well as the Italian Embassy and the Italian Cultural Institute, reflecting a coordinated effort that blended culinary ambition with cultural diplomacy.
Organizers followed strict Guinness guidelines, which required the dessert to be assembled live on site.
The scale of the operation was defined by its ingredients and logistics:
Guinness adjudicator Lorenzo Veltri verified the final length on site, confirming the record once the full dessert had been completed.
Beyond the record itself, the event also carried a charitable dimension. All proceeds were directed to the Esharelife Foundation, supporting initiatives aimed at combating poverty.
The London attempt not only reclaims the record for an Italian-led team but also repositions a traditional dessert within a global, performative context, where scale, symbolism, and international collaboration intersect.
