Osaka 2025: Doki Doki in six desserts

At World Expo 2025 in Osaka, Luxembourg is promoting its culinary expertise alongside its heritage, economic strength and innovative spirit. The focus is on delectable sweet treats, especially desserts.

Six pastry chefs from Luxembourg were invited to rise to the challenge and come up with a dessert that would combine the best of Luxembourg and Japan, while also reflecting the theme of the pavilion: "Doki Doki – The Luxembourg Heartbeat". They had to follow certain rules: use seasonal products, apply sustainability principles and opt for local ingredients to limit the need for transport. The desserts were designed to accompany the culinary section of the Luxembourg Pavilion.

Six pastry chefs, six desserts, six moods

In Osaka Bay, Luxembourg is showing off its expertise in patisserie with succulent creations produced by some of the country's best pastry chefs. It should not be too difficult for Luxembourg's pastry chefs to captivate the taste buds of visitors from Japan and other countries with their sophisticated recipes. The traditional Luxembourgish cake Bamkuch is already known and appreciated in this year's host country.

But each of these mouth-watering confections is about more than just the pure pleasure of good food – the idea is to reflect cultural diversity and promote Luxembourg's culinary expertise.

We asked each of the six pastry chefs not only what dessert they chose to make, but also why they chose it and what emotion they wanted to conjure up. 

Archibald de Prince – Williams Pears Meet Nashi Pears

"With this dessert I wanted to invite visitors to discover Williams pears, traditionally grown in Luxembourg orchards, and Nashi pears, traditionally grown in Japan, subtly blended and served under a crunchy white chocolate dome. I was keen to promote a Luxembourgish product at the World Expo and to combine it with a local product from the host country."

Paul Bungert – Black Forest

"I chose the Forêt Noire, or Black Forest, because it is a typical regional dessert. Every time I eat it, I find the flavours and different textures simply irresistible. I also chose it because I knew I would be able to incorporate Japanese products, like cherries and the country's excellent whisky, which reflect traditional know-how passed down through many generations."

Stéphane Muller – Coeur de Joie

 

"My inspiration for the Coeur de Joie (Heart of Joy) came from the Doki Doki theme – I wanted to get hearts beating in Osaka with a dessert that was both vibrant and delicate."

Pauline Michelin – Honey & Sudachi Fusion – Voyage from Luxembourg to Osaka

"My creation blends Luxembourgish and Japanese traditions – for example it combines a typical biscuit from Luxembourg soaked in saké, a Japanese citrus fruit known as sudachi, and honey from Luxembourg. The dessert celebrates the harmony between two cultures through unique, elegant flavours. Honey, a universal and eco-friendly ingredient, emphasises our commitment to biodiversity. We wanted to invite visitors to savour a dessert that is both environmentally friendly and steeped in history.

Kiyohara Yurie – Doki Doki Matcha Mirabelle

"I chose mirabelles because I thought that not many people in Japan would be familiar with them. I decided to introduce this traditional Luxembourgish fruit to Japan in an original, subtle way by combining the bitterness of matcha with the sweetness of mirabelles."

Carole Goerend – Sakura

"For Expo 2025 Osaka, I came up with a dessert named "Sakura", inspired by Japanese culture. I wanted to conjure up the magic of a stroll under the emblematic cherry trees in full blossom, where every petal reminds us of the ephemeral beauty of the present moment. Black sesame adds an almost mystical depth, while cherries, both soft and vibrant, provide a touch of passion. This dessert is a sensory journey, a tribute to the delicate balance between nature, tradition and emotion."
