You think you know, but you have no idea.

The Grand Gelinaz Shuffle, a worldwide production in which chefs swap lives and/or recipes for a short while, is back for one night only on Dec 3. And Gelinaz, an extensive collaboration between chefs across the globe, is throwing a curveball this year by keeping all the chefs in their own kitchens, and instead swapping a grand total of 2,200 recipes across the world.

Unlike previous editions, this year every chef has already received eight new recipes, but without knowing which restaurant they originated from. The chefs must then undo the recipes, remix them and create eight completely new dishes from them.

The Bangkok chefs and restaurants taking part are Garima Arora of Gaa, Tim Butler of Eat Me, Thitid “Ton” Thassanakajohn of Le Du and Bo Songvisava and Dylan Jones of Bo.lan—all of whom boast some impressive culinary chops. You’ll pay B6,000 and up for eight courses, knowing who’s cooking, but not knowing any of the dishes.

Worldwide, the list of participating chefs includes none other than Massimo Bottura of Osteria Francescana, Rene Redzepi of Noma in Copenhagen, Ana Ros of Hisa Franko in Slovenia, Niki Nakayama of N/Naka in Los Angeles, Vladimir Mukhin of White Rabbit in Moscow and Zaiyu Hasegawa of Den in Tokyo. Expect some wild creations considering those names.

People with allergies and dietary restrictions might not be catered to, however, so take note before booking. Go here for more information and to reserve your seat.
