The update is broken in that when I try to change some property it changes for the wrong recipe and mixes properties up.
Also, I was only able to create 5 tests.
The code for adding the ingredients from `recipe_attr[:ingredients]` and `recipe_attr[:new_ingredients]` is essentially identical. It should be refactored into its own method or you could just combine the two hashes with like so:
```
ingredients = recipe_attr[:ingredients].merge(recipe_attr[:new_ingredients])
ingredients.each do |key,value|
…
```
