Constructing for administrators?

I'm using the restful_authentication's current_user. So to find a user's
recipes, I use:

I want the admin (I have an "admin" column in the users table) to view
all recipes. I'm doing this right now, but think its too verbose:

@recipes = current_user.admin? ? Recipe.all :

Is there a more efficient way to have the admin view all recipes (and
non-admin only to view their own recipes) instead of doing the above?

You might think of an index all that is accessible only to admin.

before_filter :check_admin_role, :only => [:index]
