[Rails] Newbie problem with RoR - stack level too deep

[Bill Walton]

Greetings!

I'm new to Ruby and Rails and am working through the Curt Hibbs article.  I
created the model and controller per the article but I'm getting an error
message (title: SystemStackError in Recipe#new; message: stack level too
deep) when I point my browser to http://127.0.0.1:3000/recipe/new

Any ideas what I'm doing wrong?  Any help is very much appreciated!

Best regards,
Bill
