scaffold is, according to http://api.rubyonrails.com/ a public instance
method of ActionController::Scaffolding::ClassMethods.

The RDoc page can be found here:
http://api.rubyonrails.com/classes/ActionController/Scaffolding/ClassMethods.html

What it does is it adds a number of instance methods to the controller
class from where you call it. In this case, RecipeController.
