If you're looking for cooking jobs abroad, the better question is probably "why shouldn't I teach cooking at camp?". You'll spend 8-10 weeks from June to August making yummy snacks, and it's up to you to decide what they are. Whatever you're in the mood for on any given day, you can make it at camp. It's a little like working a chef's job abroad, except that you'll be cooking for yourself (and your campers).
You can make cookies, cupcakes, or delicious s'mores, or throw in a healthy option when you feel like you need to ease off a bit. Teaching your campers about nutrition, and how to choose healthy foods, is an important job - especially in the "convenience food culture" of the modern world.
If you're interested in jobs with cooking involved, and would like to pass on your knowledge and passion to others, pop your application in and get ready for your summer of a lifetime.
