Seems similar to the book How to Build Your Own Country (CitizenKid). I am comparing the two obvisouly one is free and the other isn't unless you check it out from the library.

One of the items in the container has to be a recipe. We use these later to have a "Celebration of Culture" where we enjoy sampling food from around the world.
