nice simple `Recipe` Class. since the ingredients list is always the same array for any Recipe object (`recipe1.ingredient` will be exactly the same as `recipe2.ingredient`), "ingredient" doesn't have to be an input for the `initialize` method. example:

```ruby
def initialize title, url
 @title = title
 @url = url
 @ingredient = ["eggs", "chicken", "beef", "pork", "cucumbers", "lettuce", "fish", "rice", "noodles", "bread"]
end
```
