Cookbook from HELLLLLLLLL

I'm afraid I approached the forms in a horribly wrong way. I know we were supposed to use form_tags, but I couldn't make sense of that approach when trying to add in Measurements or create the edit form, so I ended up manually putting my Measurements and Ingredients in with the form_for. 

I also deleted Measurements objects when editing them and then just creating new ones because it made more sense to me. 

Please show me the way.
