You shouldn't need to include all these <head> tags outside application.html.erb.
| @query = params[:query] | ||
| @results = EdamamApiWrapper.search_recipes(@query) | ||
| if @results['hits'] != [] | ||
| @results = @results['hits'] |

This work of parsing the response should probably be done inside the API wrapper. One of the big advantages of structuring the code that way is that it isolates your program's dependency on the API, but here that dependency is leaking out.
Lib code is similar to model code in that you should push as much functionality there as possible.

This method should be examining the response, checking for errors and returning a collection of Recipes, rather than the raw response.

|
||
| if response.parsed_response == [] | ||
| raise ApiError.new("Recipe does not exist") | ||
| end |

I like this method a lot more, but there are still some error cases you're missing. The big one in my mind is when the API keys are not set up correctly, for example if a new teammate were to download your project and miss that step of setup.
| response = EdamamApiWrapper.search_recipes(query) | ||
| response.must_be_kind_of Hash | ||
| response.length.must_be :>, 0 | ||
| end |

This is a good success case, but I would be interested to see what happens when you search for something that returns no results.
| proc { | ||
| uri = "whatacrazyurihehehehehehe" | ||
| EdamamApiWrapper.show_recipe(uri) | ||
| }.must_raise EdamamApiWrapper::ApiError |
