A couple suggestions on this line:

The first is a little nitpicky, but you're creating an instance variable `@new_ingredient`, where I believe you don't need to be. Generally, you only create one of those if you need to use it in a view or another method; it looks like it's not being referenced again. So you could probably drop it entirely:
` @recipe.ingredients << Ingredient.create(name: @attributes[:ingredient][:name])`
