At first, the pastry chef realized that the product was very sweet and wasn't rich or varied in taste. So he thought about how to improve the flavor. "From then on, I began to devote myself to developing the special features of new macaron products," Herme points out. "It can be said that in the world of macarons, no one has gone so far and so hard as me."

As a fanatic of macarons, Herme cooperated with the French Space Agency to send macarons into space a few years ago. These special macarons, which featured the initials of French astronaut Thomas Pesquet, were specially created for consumption in weightless conditions.

Early in June, Herme cooperated with ice cream brand Haagen-Dazs to launch a new macaron ice cream series called "French it up" in Shanghai. The series, which contains three flavors: strawberry, raspberry, and chocolate and lemon grapefruit, was previously only available in Britain and France starting in February.

"I am very excited and proud of our new collaboration. For the past 20 years, I have been continuously creating and reinterpreting my macaron creations, which is also my favorite and proudest field of creation. Macarons are my identity, so I seek to work with great brands," said the chef during his Shanghai tour.

In addition, he also regularly collaborates with furniture, decoration and jewelry brands to launch crossover products, for example, making beautiful "unique gift boxes", he says.

He adds that they also jointly launch products with fashion brands, such as some jewelry brands in India. "I hope to make a living art universe with the macaron at its core," he says.
