body: Say there's website X that features a bunch of recipes authored by themselves. The recipes feature
  
  
  Afaik you can't have copyright on a recipe, only on the imagery and textual description of how to prepare the recipe.
  
  
  Say I scrape all these recipes and their data (nutrition, ingredients, etc) and use it in my app to do calculations. Based on these calculations I display a link to my users to the page that contains the recipe on website X. 
  
  
  1. Would this be legal?
  2. And what if I use their image and recipe title, still linking to website X's recipe.
  3. And what if I generate revenue with my app.
