The world’s thinnest chocolate measures just 0.03 millimetres in thickness and is the creation of Japanese confectioner Matte.
Known as Corteccia, the chocolate consists of a rolled sheet and is regarded as a unique sweet product. The product was launched in February 2024 at Azabudai Hills Garden Plaza in Tokyo, Japan. Following its introduction, Matte Bottega del Cioccolato quickly gained recognition for producing the world’s thinnest chocolate.
Corteccia, a name derived from the Italian word for tree bark, is the company’s most famous sweet item. It is regarded as a remarkable feat of engineering, as producing chocolate only 0.03 millimetres thick is an exceptionally difficult task.
Inspired by traditional layered chocolates from Italy, Corteccia consists of an ultra-thin layer of chocolate that is pressed and rolled through a specially designed machine. The machine was developed in collaboration with local machinery specialists after around 18 months of work.
Although many machines of this type exist around the world, none is known to produce a chocolate layer as thin as Corteccia.
The concept behind the product was to create a chocolate with an unparalleled texture that melts almost instantly in the mouth. According to Matte founder Matteo Sanclica, chocolate is at its best when it begins to melt as soon as it is placed on the tongue.
The 0.03-millimetre chocolate layer is rolled into a cylindrical shape resembling a twig covered with irregular tree bark. The company says the chocolate melts immediately upon touching the tongue, creating a distinctive flavour and texture.
