The best way to learn someone's native cuisine is to step into his or her kitchen. And several cross-cultural cooking organizations let you do just that. The New York-based League of Kitchens invites small groups of curious cooks into the homes of women from all over the world for socially immersive classes in cuisines ranging from Lebanese to Bengali. In Buenos Aires, a couple welcomes students into their kitchen to learn how to make empanadas and Argentinian pastries at their Tierra Negra cooking school. And while its classes are taught in a community center, Seattle's Project Feast lets you work alongside refugees from countries such as Iraq and Burma, learning how to cook what they cook at home.
