Gamjeongseon Project in Seoul runs baking classes where participants make madeleines, financiers, and chewy cookies themselves, along with mirror drawing. First-time participants can follow the instructor's directions to make and decorate the desserts. While the baked goods are in the oven, participants decorate takeout containers, and for mirror drawing they can use Instagram designs as reference. The door has been locked at the reserved time, and classes have started 20 minutes late.
